9-11: exercises; Cheyenne Mt call to NEADS, routine admin request

Background

Previously, I have written about the inadequacy of the Alderson transcription of NEADS audio files.  I recommend that researchers and historians use the transcripts in conjunction with the audio files and, if appropriate, the radar files.  In other words, rely on primary source information.  The purpose of this article is to demonstrate how an apparent dramatic call, out of context, from Cheyenne Mountain to NEADS, turns out to be a simple administrative action, not apparent from a simple reading of the Alderson transcript.

Introduction

The relevant conversation is contained in NEADS audio file DRM2, DAT1, Channel 20, SD2 position.  The audio file was recorded at the position of Captain Brian Nagel.  He was dealing with track B089 (D 1989); the track that NORAD in the aftermath will conflate with concurrent information received about UA 93.

Nagel was busy trying to generate fighter assets from anywhere he could get them; Syracuse, Selfridge, Alpina, Springfield, and Toledo are mentioned.  Approximately 10:12, Nagel received a call from Captain Taylor, Cheyenne Mountain tech control.  Taylor asked that exercise inputs coming into Cheyenne Mountain be terminated.

Nagel, busy with real world activity, simply gave Taylor and administrative number to call.  The call, 101200 Cheyenne Mt Call, lasted just 15 seconds.  Nagel effeciently and effectively handled the call; it had no impact on his work.  In fact exercise activity is never mentioned during Nagel’s work to generate additional fighter resources.

A listen to Nagel’s work will serve researches and historians well as they strive to put together the pieces of the NEADS story.  Nagel’s position was “SD2,” Senior Director 2.  He worked directly for the Senior Director, Major Fox.

9-11: UA93; impact time, seismic data considered

Introduction

I recently obtained some of the seismic data concerning UA 93 and that provides an opportunity to discuss an old issue about 9-11, the impact time..

Readers may recall that there was at one time some speculation that a study based on the seismic data suggested that UA 93 impacted at 10:06, three minutes later than all available primary source information indicated.  The Commission Staff treated that speculation seriously and ran the issue to ground. 

This article is the story of the data and of how the Staff dealt with one of the 9-11 family questions.

Data Source

The Incorporated Research Institution for Seismology (IRIS) has protocols for assisting educators, researchers, students, committees, and the public.  The link provided is to the protocol for researchers.  I found the IRIS staff helpful in obtaining the information available.

To run the data I used GEE, Global Earthquake Explorer, and an IRIS-provided link to AmaSeis. (Amateur Seismometer).  Readers with seismology experience will find additional programs available from IRIS at the same link.

My point of contact provided me the files I actually used.  He obtained them by submitting a Seismic Query to determine what data were available.  He then submitted a request via email using BREQ-FAST.  Finally, he converted the files to .SAC format via rdseed.

The Data

An undated report, “Seismic Observations during September 11, 2001, Terrorist Attack,” concluded: “we infer that the Flight 93 crashed around  14:06:05 +/- 5 (UTC).”  The primary author, Won-Young Kim considered data from four seismographic stations.  From closest to Shanksville to the furtherest, the sites were: Mont Chateau, (MCWV); Standing Stone, (SSPA); Soldier’s Delight, (SDMD); and Millersville, (MVL)PA.

In his vertical component assessment, Kim initially considered all four seismic stations.  He assessed that the signal to noise ratio was too small for both the closest site (MCWV) and SDMD, on the order of 1:1.  Therefore, he reduced his analysis to the Standing Stone station where the ratio was 2.5:1.  He also established that the ratio at the most distance site, Millersville, was about 2:1.

Kim based his analysis on the Standing Stone station only, ignoring the fact that the data from the closest station was inconclusive.  Further he extrapolated only two minutes of data beginning with an estimated origin time of “14:06:05 (10:06:05)”  We have no evidence that Kim examined earlier times, specifically 10:03.

IRIS has available only the data from Mont Chateau and Standing Stone, the two stations closest to Shanksville. My contact provided 10 minutes of data, from 10:00 to 10:10.

I examined the data as far as my expertise would take me (undergraduate geophysics classes) and found nothing anomalous to support a time of 10:06 rather than 10:03.  I leave it to practicing seismologists that might be interested to provide a more definitive assessment.

Let’s now return to the issue raised to the Commission.

The Question Posed

A 9-11 Family Member told  me via e-mail that seismologists agreed that UA 93 crashed at 10:06, not 10:03 as NORAD said.  I took that request for action and we obtained a copy of the report.  It was not a U.S. Army document; the Army referred us to the Maryland Geological Survey website for a copy.

We found that the time in the study, 10:06, was at odds with all other primary source information, the convergence of which supported a crash time of 10:03.  Despite that convergence we took the time to fully consider an alternative time of 10:06, as requested.

Primary source information

Data from the UA 93 Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR), air traffic control communications, FAA radar, and Air Force radar established a crash time of 10:03.

The seismic data was also primary source information; the study that inferred at time of 10:06 was not.  Statements that the seismic data show that UA 93 crashed at 10:06 are inaccurate.  Further, statements that leading seismologists and scientists concluded that UA 93 impacted at 10:06 are disingenuous.  The work was that of a single person, as it turned out.  Here is how we proceeded.

Steps taken

The study was sponsored by the Department of Natural Resources, State of Maryland under contract number SMGS/AG1-01-075.  The authors were Won-Young Kim, Lamont-Doherty Earth Observatory of Columbia University, and Gerald R. Baum, Environmental Geology and Mineral Resources Program, Maryland Geological Survey.

Our first step was a request to the Maryland Geological Survey (MGS) asking them to validate and verify the study done by one of its employees. The MGS declined stating that the work was primarily that of Won-Young Kim and that we should address our request to him.  The MGS, literally, walked away from the issue.

The second step, then, was to contact Mr. Kim, which I personally did.  Over time, I exchanged a series of emails and phone calls with Mr. Kim.  I informed him that multiple other primary sources of information did not support his work.  His position was that, if so, he still had confidence in his work.  Ultimately Mr. Kim agreed to a statement that the seismic data was not conclusive concerning the crash of UA 93.

Given that statement, we reconfirmed that the preponderance of evidence supported a time of 10:03 and that became our position.  There was, however, another avenue we could explore.

Going the extra step

Even though we had a high degree of confidence in the 10:03 time, we decided to treat the two times as equal and sought and obtained additional primary source information, infra-red satellite data.  We asked the Defense Special Missile and Astronautics Center (DEFSMAC) for the times it had established for the impacts of all four hijacked planes.

We had noticed in the Cheyenne Mountain Operations Center (CMOC) logs that some “IR [infrared] event” times had been entered that morning and assumed that DEFSMAC had recorded all four “IR events.”  They had, and the data provided was consistent not only with the 10:03 time for UA 93 but for the other three impact times, as well.  The DEFSMAC response is in the classified Commission files held by NARA.

To put it another way, we gave the two disparate times–10:03 and 10:06– equal weight and went to a tie breaker, even though there was no compelling analytical reason to do so.

A comment on DEFSMAC

Accurately reporting “IR events” is vital to the defense of the nation.  Missile launches are serious business and DEFSMAC provides the earliest possible indications and warning of  such a potential threat.  The DEFSMAC times, alone, are sufficient to establish the impact times of the four hijacked aircraft.

In the end

We spent considerable time running the seismic issue to ground.  Yet the answer did not matter, it wasn’t the “right” answer.  During the reading of Staff Statement 17 at the final air defense hearing we presented the list of sources for 10:03 time of impact for UA 93.  Behind us, someone in the audience commented, what about the seismic data?

Questions answered that don’t provide the expected or wanted answer become…more questions.

9-11: The Otis Scramble; a puzzling event, explained

(Author’s note.  I will add relevant audio clips after I obtain all the files)

Introduction

The public domain explanation for the Otis scramble is simple and straightforward: the Northeast Air Defense Sector (NEADS) learned of a hijack in Boston airspace and launched alert fighters, which flew, direct and supersonic, to defend New York City.  None of that conformed to the reality I saw when I first ran the 84th RADES radar files and saw not a direct flight, but a path resembling a pretzel.

We asked General Craig McKinley, General Larry Arnold, and Colonel William Scott to clarify that for us at the May 23, 2003, air defense hearing.  They did not, and possibly could not because they had never sorted it out.  One example of their inability: Colonel Scott blurred the path of the Otis fighters, blaming to Commission Staff in a later interview the inadequacies of PowerPoint.

So how did the Otis scramble actually proceed?  There is not and will not be a complete primary source historical record for the specific guidance and direction given by NEADS to the Otis fighters.  In a previous article, I established that the audio channels at NEADS for the Otis flight military controllers were not recorded the morning of 9-11. However, one of the controller voices, most likely the WD/T, was recorded at FAA’s Boston Center (ZBW), Cape Sector, during the time the fighters were vectored to Whiskey 105.

Even with limited primary source information for the NEADS controllers, we have enough other primary source information–NEADS tapes, FAA air traffic control tapes, radar–to explain what happened. We cannot, however, explain why the Otis fighters ended up over New York City.

Useful Commission Work Papers

I created screen print slide sets for planes of interest–the hijacked planes, fighters, and observers, such as Gofer 06 and the Falcon Jet vectored to the Shanksville site.  The set for the Otis fighters can be found at this link.

Another useful source is a compilation of the air traffic control contacts with the Panta flight.  (Panta 45 and 46 Scramble Timeline)  The flight was controlled by CAPE TRACON until Boston Center (ZBW), Cape Sector (18RA) gained radar contact at 8:55.  Thereafter, FAA contact was continuous as the flight was passed from Cape Sector to ZBW, Hampton Sector (31R) at 9:01, and then to New York Center (ZNY), Kennedy Sector at 9:17.  Ultimately, Panta 46 was handed off to Kennedy Approach (N90) at 10:10.

A third document, a chronological compilation of condensed audio transcripts, is a useful guide to conversations recorded at NEADS.

A fourth helpful document is a draft “Otis Story Board.”  This was a work paper created to provide a list of potentially useful audio clips for an oral monograph.  (Team 8 wrote the monograph, but it was not published because we ran out of time.  The draft should be available in the Commission’s electronic files, once they are released.)

There are multiple other useful work files, but the four listed are sufficient for the task at hand.  We begin with the scramble order.

The Scramble

NEADS obtained operational information, a set of coordinates, at 8:40, the notification time from FAA as entered in the MCC/T log, the official log book of the day.  The Otis fighters were placed on battle stations soon after 8:41, the scramble order-heading 290, flight level 290—-was issued at 8:46; and the air defense fighters, Panta 45 and 46, were airborne shortly after 8:52.  It was a rapid response, but NEADS did not have a target.

Joe Cooper at ZBW told Major Dawn Deskins at NEADS that “it’s just a primary, we lost mode so you’d have to get up and we would have to vector you.”  Deskins responded, “Okay you’d want to control intercept because…,” and Cooper broke in and concluded, “We’d have to until you pick up on primary.”

This exchange just before 8:40 established that FAA would always control the fighters, which they did.  Lynn Spencer’s narrative to the contrary, AFIO (Authority For Intercept Operations) was never declared for the Otis fighters.  Nor, according to the 84th RADES radar files, did they ever squawk AFIO, “quad sevens,” 7777.

Fighter speed, a useful source

A short digression at this point is in order.  A press release, “Air Force Says 911 Interceptors Flew Slow,” was released on November 17, 2003.  The argument was based on the NORAD timeline of events on 9/11, which stipulated that a rate of progression of .9 Mach could be used for fighter speed.  The NORAD staff wrote two point papers in response, one written by an officer in NJ33 (an operations office) and the other by Cheri Gott.  The two papers, combined, provide explicit information on how fast the Otis and Langley fighters flew, and why.  They also provide additional insight as to why fighters at Andrews AFB were not considered as a reaction force.

Now back to the Otis scramble.

NEADS did not find the primary target but did establish a “Z” point at 8:44 based on the coordinates provided by ZBW.  At that time AA 11 was well south of the “Z” point, rapidly approaching its own target.  Even though a fixed point was established, contemporary records reveal that NEADS altered its own plan to vector the fighters to that point, as we shall see.

Standard scramble procedures

As was the case with the Langley fighters later, Panta 45 and 46 launched to the east (runway 5) and proceeded toward Cape Cod before turning back at 8:54 at an altitude of 10,000 feet.  It was standing operating procedure that air defense fighters would take off easterly and fly runway heading to a certain altitude or distance.  Those standard tactics, techniques, and procedures allowed for routinized transition to FAA control and safety in the air.

Here is a Google Earth image of Otis AFB, Dec 2001.  Note that the alert area was at the southwestern end of Runway 5, with a dedicated short taxi strip.  The same configuration applied at Langley except that the alert area was on the north side.

At both facilities the fighters had the ability to start takeoff from the taxi strip.  Also, at both facilities, the pilots had the ability to “back taxi” the runway and take off westerly: this was an available procedure, but one that was rarely used.

In sum, the Otis fighters were quickly airborne and ready to fly somewhere, but the scramble order did not provide two necessary elements of information, a distance to fly and a target to find.  NEADS had an option of vectoring the air defense fighters to a military training area, Whiskey 105, and that’s exactly what happened.

Whiskey 105 and Giantkiller

Whiskey 105 (W105) is one of many offshore military training areas; its westernmost extension is southeast of New York City.  Aircraft operating in any such area come under the control of Giantkiller (Fleet Area Control and Surveillance Facility, Virginia Capes, Oceania Naval Air Station, Virginia Beach, VA), a Navy-operated facility and one recipient of the scramble order.

Giantkiller played a brief role in the control and vectoring of both the Otis fighters and the Langley fighters.  However, the only time we hear the voices of Giantkiller is when they appear on either FAA tapes or NEADS tapes.

Giantkiller long-standing policy was to recycle its tapes, and that is what they did post 9/11.  No one in the Giantkiller chain-of-command gave them instructions to alter the policy and retain the 9/11 tapes.  No one at Giantkiller had the presence of mind to realize that their tapes might be a valuable primary source of information concerning events of the day.

Getting to Whiskey 105

Whiskey 105 was activated by Giantkiller after the Otis fighters launched and before they turned back to the west.  Shortly before 8:50 that fact was reported to ZBW Cape Sector.  Minutes earlier, the NEADS Mission Crew Commander (MCC) Major Nasypany, summarized the situation for Colonel Robert Marr in the Battle Cab.  “I have scrambled Otis, and already, as per your direction, we’re sending them in that general direction, we’re sending them right to that Z point, and then we can maneuver them, um, as deemed uh right.”

By 8:51, however, NEADS knew that a plane had hit the World Trade Center.  Still, just before the fighters turned the MCC said, “send them to New York City, still considered a go.”  He then changed his mind.

“Okay, continue taking the fighters down to the New York City area, JFK area, best that we can, make sure the FAA clears your route all the way…just press with it.”  And then, “until it’s confirmed it’s gonna be a lot easier to get them down to this area [Whiskey 105].”  “…if he didn’t crash into the world trade center [he] is 20 miles south of JFK, so I want you to take them down into this area, hold as needed.”

The FAA transcript for Boston ARTCC Cape Sector, Sector 18, Radar position, is definitive on what happened.  The transcript shows that FAA, NEADS, Giantkiller, and Panta 45 worked together to vector the fighters, first on a heading of 260 vice the scramble heading of 290, and then a direct heading of 250 to Whiskey 105.

At 8:54, HUNTRESS called Cape Sector and asked to change the Panta heading: “the heading that we gave him …is a bad heading now, actually he’s now south of JFK.”  Panta 45 checked in with Cape Sector at 8:55 and was given a new heading of 260, based on Cape Sector’s conversation with HUNTRESS.

NEADS had concluded that holding the fighters south of JFK in W105 was the best course of action.  At 8:59, according to the 84th RADES radar files, the Panta flight veered slightly south and headed directly for W105.  At 9:01, Panta 45 told Cape Sector he was “proceeding our present heading of two five zero for about a hundred miles and HUNTRESS wants us to hold just south of Long Island.”

At 9:01, Panta 45 checked in with ZBW Hampton Center and reported he was looking to hold in the corner, the west end of W105.  Hampton asked him for his destination.  Panta 45 did not know.  At 9:05, Hampton informed, probably, Giantkiller that “Panta is going to hold in W105, left to right turns at 290.”

Panta awareness

The primary sources of the day are clear that the Panta flight knew about both impacts at the World Trade Center.  First, on check-in with ZBW Cape Sector at 8:56, Panta 45 was told about the crash into World Trade Center One.

Second, at 9:08, ZBW Hampton Sector told Panta 45 about the second impact.  A minute later Panta 45 told Hampton Sector he needed to move to a holding pattern over New York City, and immediately modified that request to be a CAP over New York City, if available.  Panta was instructed to navigate for the Kennedy VOR.

The Panta pilots were angry, and that anger comes clearly across in the one cockpit voice recorder (CVR) tape that is part of the Commission’s records.

The primary sources of the day include the CVR from one of the two Panta fighters and both of their HUD (Heads Up Display).  Those tapes are in the Commission master files and have not been released by NARA.

None of the three is accurately time-stamped.  Further, the HUD tapes require a knowledgeable person to explain what is displayed.  The Air Force provided such support to the Commission Staff.

Getting out of Whiskey 105

The first left turn back east in the holding pattern began about 9:09.  The MCC’s voice is actively heard on the NEADS tapes talking to both the Senior Director (Major Fox) and to the Battle Cab and Colonel Marr.  To Fox he directed at 9:08 that “we need to talk to FAA…let’s get them over Manhattan, at least we have some kind of play.”  And at 9:09 he directed a scramble at Langley, modified by Colonel Marr to be battle stations, only.

NEADS did not know how many planes were missing out of Boston, and the MCC believed he needed to get the fighters over Manhattan.  Yet no specific orders were apparently given.  At 9:10, he told probably Fox that he did not like the fighters there, W105, and he wanted them closer in.  “I want them south of JFK.”

South of JFK and over Manhattan are two different things.  At 9:11, on the guard [emergency] channel, NEADS broadcast “Panta 45 remain current position until FAA requests assistance.”  Two minutes later the Panta flight did not make the second left turn to continue the holding pattern, but broke formation and made a sharp right U-turn and headed directly for New York City, arriving over Manhattan at 9:25.

We have no primary source information that informs us as to why the Panta flight abandoned the holding pattern.  There is no amplifying information for the odd, one-time use of the guard channel to communicate with the Panta flight.

What we do know is that the MCC was not immediately aware that the fighters were on their way to New York City.  At 9:17, four minutes after the Panta flight abandoned the holding pattern, the MCC told Colin Scoggins at Boston Center that, “I’ve got fighters in Whiskey 105 rignt now, and I’ve got a tanker there as well, I’ve got other aircraft on alert at Langley as well.”  “I’ve got trackers [looking] over JFK…just looking for anything suspicious.”

Moreover, at 9:22, after learning of the rebirth of AA 11 as a threat to Washington, the MCC wanted to “take the fighters from Otis and chase this guy down if I can’t find him.”  By then, the Panta flight was over Long Island quickly approaching New York City.

Panta flight under FAA control

As of 9:09, Panta 45 had approval from Boston Hampton Sector  to move to a holding pattern over New York City and was told to navigate to the Kennedy VOR.  That was the time that the Panta flight entered the holding pattern in W105.  The problem was that they were actually in Giantkiller-controlled air space and Hampton Sector had no control authority over New York City airspace.

Giantkiller asked for the Panta frequency shortly after 9:11, as the Panta flight was transiting west to east in its airspace.  Concurrently, Panta 45 told Hampton Sector that he was talking to HUNTRESS.

HUNTRESS is NEADS, and it is that conversation that we do not have because console 19, the console for the Weapons Director and the Weapons Director/Technician for the Panta flight, was not recorded.

Time for a short summary

Let’s step back a moment and assess what we have.  We have Panta 45 with FAA (ZBW Hampton Sector) approval to move to a holding pattern over New York City.  That approval was modified to be a controller direction to navigate to the Kennedy VOR.

We have the Panta pilots angry and, from their view, headed in the direction from which they came, not the direction of the visible evidence of the attack.  We know that they knew about both crashes into the World Trade Center.

We have the MCC under the assumption that the fighters are at his tactical direction in Whiskey 105, and we have NEADS broadcasting on guard for the Panta flight not to go to New York City without FAA approval.  They knew that FAA’s New York Center had issued an order for no more planes to enter its airspace.

So, what happened?

Absent the audio files from the NEADS controllers, we do not know what actions they took, and when.  What we do know is that at 9:14, the MCC told Colonel Marr that “we got [a tanker, MAINE 85] going to W105 right now, we also have the fighters holding there, we’re trying to move them down south of JFK, okay, we got some bad poop from FAA.”

The “bad poop” reference is possibly a reference to the original coordinates that established the “Z” point.  As the MCC was briefing Colonel Marr, the Panta flight was no longer holding in W105 and was not just navigating to the Kennedy VOR; it was headed directly for New York City.

Back to FAA control

Given what the ZBW Hampton Sector controller observed on radar, the Panta flight headed directly for New York City, he did what he was required to do: he made a “point out” to the gaining Sector, ZNY’s Kennedy Sector.  Shortly before 9:15, he pointed out the flight, “East of Kennedy 40 miles.”  Kennedy Sector acknowledged that he had radar contact, a necessary step before transfer of control can take place.

However, Hampton Sector maintained control for nearly two minutes and told the Panta flight to maintain Flight Level 240, the altitude of the holding pattern in W105.  The handoff to ZNY Kennedy Sector came at 9:17, the same time that the NEADS MCC was telling Colin Scoggins that the flight was holding in W105.

Kennedy Sector assumed responsibility for the flight and worked with adjacent sectors and New York TRACON to establish the parameters of a combat air patrol, which the Panta flight entered at 9:25, flight level 180.  Thereafter, both Panta 45 and 46 worked under Sector, NEADS, and TRACON control to check out potential targets of interest.

My Assessment

I have puzzled over the Otis scramble for the past five years and have reached this conclusion.  Retrospectively, it made tactical sense for the Panta flight to remain in W105.  The situation was fluid, they had no target, and tanker support was arriving. There was no compelling tactical imperative to send them to a combat air patrol (CAP) over New York City.

It is understandable that the Panta flight, and perhaps their controllers, felt compelled to establish a presence over New York City.  But to what end?

NEADS had no target for them.  Further, that cut NEADS’ available assets in half, and the other half, at Langley, was still on the ground, but had gotten the scramble order at 9:24.

From 9:25, the time the Panta flight began its CAP, and 9:37, the time NEADS declared AFIO for the Quit flight, NEADS had no available air defense-capable fighters immediately ready to combat the threat to the nation’s capital.

By this time the 9:21 report of a still airborne AA 11 represented a threat from the North.  A few minutes later NEADS learned that AA 77 was missing; and soon identified the track as B-32, a fast-moving unknown threatening the capital.

So, did the Panta flight proceed with FAA approval?  The answer is yes, except that the approval was granted by Boston Center, not New York Center.  Did the Otis pilots proceed with NEADS approval?  We do not know.


9-11: The NEADS audio files; important information for Historians

Background

I have written about the Northeast Air Defense Sector (NEADS) audio files in two previous articles.  First, I explained  the Alderson transcripts.  Second, I addressed an issue–a non-issue really–raised about the Commission’s ability to obtain the NEADS files.  Both of those articles should be read before continuing with this article.

My purpose in this third article is to provide additional insight and guidance especially for future historians.  Modern day researchers and writers will benefit, but the intent is to facilitate work in the broad reach of history.  We start with the NEADS partial transcript.

The NEADS partial transcript

The NEADS partial transcript was the first secondary source document the Commission Staff obtained to provide insight into the activities at NEADS on 9-11.  Its direct and necessary complement is the first primary source information received, the radar files of the 84th Radar Evaluation Squadron (RADES).

Multiple copies of the partial transcript were archived as workpapers by the Commission Staff, each annotated or cut and pasted in some fashion.  I archived at least two copies.

The most useful, partially color-coded as to speaking voice, is available at this link.  Retrospectively, I believe this is the copy I took with me on the first NEADS visit, based on the annotations.

A second, earlier copy is at this link.  In that copy I specifically annotated an important point about the NEADS partial transcript; it is partial for a reason.

According to the transcript: “MEMO FOR RECORD: 21 SEP 01.  Due to an equipment malfunction, the rest of the information recorded on DRM 2, DAT 2 was lost.  The incident tape was in the data recorder for playback purposes by SSgt James D. Tollack, 305 OSS [Operations Support Squadron], McGuire AFB, who was performing the transcription, when the computer equipment failure occurred.”

SSgt Tollack was the one person designated to transcribe the NEADS audio files in the immediate aftermath of 9-11.  He did his work at the NEADS Sector Operations Center.

The Sector Operations Center (SOCC)

NEADS had two main facilities, the Headquarters and the SOCC.  The two were located on Rome Air Force Base but physically separated by a distance of several hundred yards.  Typically, the Command and primary staff were at the Headquarters, but on 9-11 Colonel Marr and key staff were in the Battle Cab at the SOCC; there was an exercise scheduled.

My SOCC work files are available to researchers and historians.

The Tollack Saga

SSgt Tollack was the only person who listened, iteratively, to the NEADS tapes prior to the Commission Staff’s first visit in late fall, 2003. A copy of notes taken during our interview document the basic story.  Tollack said that, according to Jeremy Powell, NEADS personnel did listen to the tapes prior to Tollack’s arrival.

Tollack stated he arrived at NEADS on Sep 20, 2001; (added Jul 14, 2001) his travel voucher is for the period Sep 20 – Oct 4.  If so, his work did not inform the effort of General Arnold working with Jeff Griffith at FAA to establish an agreed upon timeline, the preparation of either agency for a White House meeting, or the release of the NORAD timeline on September 18, 2001.

A copy of Tollack’s travel orders is in the Commission’s paper files; that document will establish his time on station. (para deleted Jul 14, 2001)

Tollack worked long hours to accomplish the work that led to the NEADS partial transcript.  He did not type the transcript, but did type his notes which he gaive to two secretaries dedicated to him; they created the transcript.

Because of the equipment malfunction, Colonel Marr stopped Tollack’s work on DRM 2.  According to Marr during his inbrief for our first visit, he sequestered all the NEADS tapes to preserve them.  There was no attempt to further listen to or use the tapes between the time Tollack ceased work and the time the Commission requested the tapes and transcripts.

During our interview with Tollack I asked him about “Freedom files–should not have 20 min error.”  I will return to the Freedom Files subject later.  Tollack said there was no error in the NEADS audio files and he was, in fact, the person who discovered the 25 second error in the NEADS radar files, later documented by NTSB.

Getting the audio files

Despite Commission formal requests for a copy of the tapes and a transcript, NEADS was unable to deliver in time for our first visit the last week in October, 2003.  I arranged with our POC to obtain a copy of the tapes on site; there would be no transcript.

As agreed, NEADS provided, piecemeal, digitized copies of their tapes as Commission Staff was conducting interviews.  We worked with a copy of the partial transcript and the audio files and attempted to walk interviewees through the events of the morning of 9-11.  It quickly became apparent that the transcript was insufficient for the task at hand.  Our Team Leader, John Farmer, consulted with Colonel Marr and informed him that we were terminating the visit prior to the final interview with him.

The direct result of our termination of the visit was the issuance of a subpoena to DoD.  The audio files were delivered under a schedule provided by the Under Secretary of Defense in a November 6, 2003, memo.  There were no transcripts and Commission Staff contracted that effort, as I discussed in the Alderson article.

There was still a problem with the missing channels from DRM2.  The manufacturer, Dictaphone, took control of the tapes and was able to recover “most of the tracks,” as the Under Secretary reported in a November 25, 2003, memo.  Working with our DoD point-of-contact we were able to obtain digitized files from Dictaphone for all of the recorded channels from all three digital recording machines at NEADS.

The “Freedom Files”

The Dictaphone-provided files are the “Freedom Files,” alluded to in my question to Tollack about timing errors.  For a reason never determined, Dictaphone’s recovery process introduced a 20-minute error across the board for all NEADS audio files provided as a result of the manufacturer’s recovery process.  That error has no analytical impact except that it must be accounted for and analysts, researchers, and historians need to remember which set of files is at hand as they work.

Two sets of NEADS audio files

There are two sets of NEADS audio files in the Commission master files; the NEADS-provided set as documented in the DoD memo of November 6, 2003, and the Dictaphone-provided Freedom Files set as mentioned in the DoD memo of November 25, 2003.  Each set is useful in its own way.

The Freedom Files set has more channels, but none of the additional channels contains audio files that change anything, analytically.  The essential NEADS story is contained in the NEADS-provided files, the NEADS partial transcript, and the Alderson transcripts.

The NEADS audio files. These files are accurately time-stamped.  Researchers, however, need to make sure they line up clock time and tape time as they work with the files.  The files have the advantage of containing all the dead space, and some of the channels are just that, dead space.

It is not analytically useful to listen to the tapes using a basic media player.  A program such as Adobe Audition provides an easy way of identifying dead space, locating potential recordings of background conversations, and reducing noise and clicks.

I strongly recommend the NEADS audio files for researchers and historians, especially those examining the NEADS audio files for the first time.  Those files are in the public domain.

The Freedom Files. These files are not yet in the public domain.  They have the unique advantage of being conversation only; all dead space is eliminated.  Each conversation segment is time-annotated from the basic NEADS time clock, but does have a 20-minute offset.

Some of the conversation segments approach 30 minutes in length.  These are the information-dense segments from the MCC, ID, SD, and WD areas where conversation was near continuous.

The Freedom Files are extremely useful for researchers and historians who are familiar with the NEADS floor conversations and are looking for specific conversation segments.  Toward the end of our work I tended to use the Freedom Files almost exclusively, for example.

Two Channels not recorded

Nowhere in either set of primary source audio files from NEADS do we hear the voices of the controllers–the Weapons Director and Weapons Director/Technician–for the Otis fighters.  There is no primary source information that tells us how and why the Otis fighters established a combat air patrol over New York City, despite Lynn Spencer’s narrative in Touching History.

But that is a story for another article.  For our purpose in this article it is sufficient to identify the two channels that were not recorded.

According to my SOCC work charts, one console, ODC 19 was not recorded.  ODC 19 was the position for the Otis controllers.  The two channels missing are channels 15 and 16, DRM 2, according to the matrix on the second page of my archived work files.  That second page is a summation page and is more accurate than any following chart.

We asked Dictaphone for a determination as to why the two channels were not recorded.  Dictaphone could not make a forensic determination because the SOCC equipment suite had changed too much since 9-11.  It was, however, their judgment that the two channels were, for whatever the technical reason, not recorded on 9-11.

I agree with that assessment.  Anyone who has listened to the NEADS tapes knows that there is a cacophony of sound, especially at critical times.  It was that feature that caused Alderson to conclude that it was easier to try and follow individual voices.

That cacophony was caused, in part, because individual channels recorded side by side on the master tape bled over to each other during the process of copying individual channels to digital form.  For example, the voices of the Langley controllers are heard on multiple channels.  On the contrary, the voices of the Otis controllers are never heard, there was no bleed over because there was nothing to bleed.

What’s next?

This concludes our discussion of the NEADS files, a necessary step before the Otis scramble can be discussed, given that the military controllers for that scramble were not recorded.

I will refer back to this article when we begin our discussion of the Otis story.

9/11: AA 77; Flight Data Recorder, a definitive analysis

This short article serves to document the work of Warren Stutt.  Warren has taken it upon himself to parse the data from the AA 77 flight data record down to its most elemental level.  His work is definitive and significantly extends the work of the Commission on this issue.

For those interested in definitive, supportable research on the technical details of the flight of AA 77 this is your best source.

9-11: AA 77; detailed work on the radar coverage issue

There is a dedicated group of individuals who are working diligently and thoroughly to document technical information pertaining to the flight of AA 77.  Their work builds on the work of the Commission and extends that work in depth and detail. One such individual is Tom Lusch whose interest is the radar coverage issue.  Here is a portion of his vitae.

Tom Lusch is a Certified Professional Controller with over 28 years of experience in the enroute, terminal, and tower options of the Federal Aviation Administration’s air traffic control system.  In 1992, a paper he authored, “Real Targets – Unreal Displays: The inadvertent suppression of critical radar data” was republished in the Journal of Air Traffic Control (link) His treatise focused on the low-altitude environment.
 
As demonstrated with the vanishing of AA 77 from the screens at Indianapolis Center, the processing of multiple radar data remained a challenge for the FAA.  On his web site he counters the contention that  there was “…poor primary coverage where American 77 was flying.” (link).  His thesis is that the problem was radar data processing not radar coverage.
 

9-11: UA 93; headed for Washington National

The purpose of this brief article, published under the UA 93 category, is to document primary source information concerning the new flight plan for UA 93 with destination Washington National.

The audio file was recorded at Position 14C, Herndon Center, on a tape with the title: 5 DCC 1933 Ops Phone 5140, Position 14C 1315-1415 UTC.  That position received a call at 10:04:25 after UA 93 was down asking if the Command Center had the “strip” on UA 93.  The unidentified caller reported a call from New York Center that the plane departed Newark and was “inbound to Washington National.”

That call confirms that the new flight plan and destination for UA 93, as entered in the system by Cleveland Center, was available in the Traffic Display System.

The conversation can be heard on this clip. 100425 UA 93 Headed to Washington National

9-11: UA 93; airphone call, not a cellphone call

This short article provides an example of how the terms “airphone” and “cellphone” became conflated and confused right from the first reports of use.  The pertinent conversation was recorded at Operations Position 28, Herndon Center, a few minutes after 10:00.

Great Lakes Region security notified the FAA Tactical Net of a report from the Oak Brook, Illinois, police that they had received a 911 airphone call from a passenger aboard UA 93 reporting three hijackers with knives and making bomb threats.

Concurrently, in the background another individual passed the information to someone else and substituted the word “cellphone” for “airphone.”  That conflation occurred as the report was received by the Tactical Net.

The audio of those conversations can be heard here.  100310 Airphone Call UA 93

A report that the White House, Treasury and State are being evacuated can be heard in the background at the beginning of the audio clip.  The time was 10:03, so that was a delayed report.  BBC video footage from “Clear The Skies” established that the White House evacuation began sometime after the Pentagon was struck, but  before 10:00.

9-11: Delta 1989; Addendum, Confirmed not trip by Delta

The purpose of this article is to establish that Delta Airlines did not consider Delta 1989 to be a “trip,” a hijacked aircraft.  At 9:55, Herndon Center, Operations Position 27 called Delta asking about the flight.  Delta confirmed that it was landing normally at Cleveland.

The primary source audio can be heard here. 095527 Delta 1989 not a trip

Delta Airlines considered the source of the concern about Delta 1989 to be Boston Center, ZBW.  ZBW, on its own initiative, had assessed the developing situation and determined that the hijack pattern concerned transcontinental flights departing Boston.  Three flights fit that profile: AA 11, UA 175, and D 1989. ZBW shared its analysis, and what was originally an expression of concern by ZBW morphed into speculation that D 1989, itself, had been hijacked.

My understanding, using the lens of Chaos Theory, is that D 1989 became a “strange attractor,” a focal point for attention that could not be predicted.  Contorted concern for the flight became disruptive feedback into the air traffic control system during an already chaotic time.  An unknown aircraft (AA 77) had just slammed into the Pentagon.  Minutes earlier, Cleveland Center had reported that UA 93 had a bomb on board.

The conflation of events concerning D 1989, UA 93 and AA 77 persisted long after the attack was over.  Norman Mineta conflated the AA 77 and UA 93 stories.  General Arnold and Colonel Marr conflated the D 1989 and UA 93 stories.

All three internalized the events of the day in the immediate aftermath as FAA and NORAD failed to agree on a common timeline.  Their misunderstanding of events became the public story, one which persists erroneously to this day.

9-11: War Games; an update

Russian “Missile Shot”

I just rediscovered a short audio conversation at Position 22, Operations Phone 5122, Herndon Center that indicates the National Operations Manager (NOM), Ben Sliney, was aware of the Russian “missile shot.”  That primary source information is an update to my first article on “Training, Exercises, and War Games.”

The 8:17 call came from Oakland to Herdon Center asking who the NOM was and to speak with him.  Herndon Center asked the nature of the call and was told it had to do with the Russian “missile shot.”

That request can be heard here.  081709 Oakland Sliney Russian Missile Shot There is no known audio recording of Oakland’s conversation with Ben Sliney.

The threat, in perspective

For the first time in the post-Cold War era the Russians had scheduled an air-launched cruise missile (ALCM) live-fire exercise.  The exercise was ongoing the morning of 9-11.  It had the nation’s attention.

In the course of my staff work I saw the briefing slides prepared for the Chairman JCS intelligence brief that morning.  At the Pentagon, General Myers likely saw a slide depicting the ALCM threat to CONUS as part of the brief.  I estimate he didn’t spend much time on it; he simply looked to see if the threat had changed.

It was a slide he had seen multiple times over the years.  The slide I saw as part of his brief was little different from one I was responsible for maintaining in the early 1980’s while stationed at the Intelligence Center, Pacific supporting the Commander-in-Chief, Pacific Command.

General Myers likely saw the slide sometime before 7:30.   A little more than two hours later terrorists flew a hijacked commercial airliner into the Pentagon.  That was not the threat of the day briefed to the Acting Chairman, Joint Chiefs of Staff.

Addendum March 21, 2010

Background

Herndon Center tape 5DCC 1927 Ops phone 5134 Position 34 1215-1315 UTC provides additional information important to understanding how the Center worked, specifically the Strategic Planning Team (SPT) using the SPO (Strategic Plan of Operations) as the National Airspace System (NAS) operators dealt with the Russian exercise and missile shoot.  Position 34 is the National Operations Manager position.

A study done in 2000 on weather processes and product requirements provides insight to both the SPT and the SPO.  Even though the study was weather-related the procedures discussed pertain to any of the frequent planning conferences held each day at Herndon Center.

Why are planning conferences so frequent, on the order of every two hours?  Because Herndon Center is in business to manage chaos.  Nothing is more chaotic than weather.  The Butterfly Effect of weather is a defining term for chaos in the literature.  Although weather was the primary reason for a planning conference, in this case the conference was used to discuss the Russian exercise.

The study cited also establishes that one of eight large screen displays at the Herndon Center as of 2000 was the “National Traffic Situation Display (TSD).

We pick up the audio from an ongoing “SPO” conference at 8:15.  Why 8:15?  The Commission Staff requested four hours of tape from every Herndon Center position, 8:15 to 12:15, to cover the time of the four hijackings.

East Coast Discussion

As we listen in, Herndon Center concluded that Boston Center and the Canadians (Montreal) will provide a briefing at the end of the 9:15 SPO, as it was referred to by one participant.  The intended audience was the carriers and that participant asked if the European carriers could be included.  That first conversation can be heard here.  081505 Herndon Center SPO

Separate Conference Recommended

In this segment we hear the reason for inviting the European carriers.  They had “quite a few questions the other night.”  Boston Center recommended a separate telecon.  That second conversation can be hear here.  (Note this is one continuous conversation that I’ve broken up to limit the file size of any one segment.)  081550 separate conference suggested

Time Set and Changed

In this segment we first hear a time of 1400Z (9:00) recommended.  Gander suggested a later time, 1430Z (9:30) to make sure every one had the tracks.  This is a reference to declared Russian tracks.  Russia was required to issue a Notice to Airmen (NOTAM), a copy should be in the Commission master files.  That conversation can be heard here.   081653 time set, tracks mentioned

Advise Edmonton and Anchorage

Manchester recommended that Edmonton and Anchorage be advised later in the day, as well.  The reason was to make them aware of the Russian restrictions last night (September 10) and what was going to happen tonight (September 11).  That conversation can be heard here.  081747 Advise Edmonton and Anchorage

Ben Sliney Working the Issue

In this next conversation we learn that Ben Sliney was dealing last night (September 10) with two issues (Boston/Montreal and Edmonton/Anchorage, two areas).  Ben was aware of the impact of last night and what could be expected today (September 11).  That conversation can be heard here.  081835 Ben Sliney involved

Russian NOTAM Compliance Mandatory

The last substantive question asked for confirmation that the tracks would be put out.  Herndon Center said they would put the tracks out now and a second time with a reminder that compliance with the Prestwick NOTAM was mandatory.  That conversation can be heard here.  081913 Compliance with NOTAM mandatory

Perspective

This addendum establishes that Oakland Center called Herndon Center asking to speak to Ben Sliney while a national planning conference was ongoing to address the Russian exercise.

Herndon Center had long established procedures in place to manage extraordinary events.  It handled the Russian exercise in a simple and straight forward manner.  All parties had their say and consensus was reached on who needed to know what.  Russia was in compliance and had issued a Notice to Airmen.  The Russian exercise had no impact on the NAS and only limited impact on the existing air defense posture.

Two “areas” are mentioned; Boston/Montreal and Edmonton/Anchorage.  We know that the air defense response was to forward deploy air defense fighters in Canada and Alaska and that the dedicated air defense fighters on the east coast carried added fuel tanks and armament.
