Flight 93
Maps, discrepancies, photos, debris, flight paths and other information.





Shortly after 9 a.m., a message, automatically sent to all United Airlines pilots by the home office, had flashed on the cockpit computer screen. It notified them that American Flight 11 had already crashed into the first World Trade Center tower and United 175 had just plowed into the second tower. They were also told that American Flight 77 had been hijacked and was headed for Washington. D.C. That message was followed by a general warning and three ominous words: "Beware, cockpit intrusion."
One of the pilots typed. "Confirmed."
Unknown to the passengers till later, American Air­lines Flight 11 had crashed into the North Tower of the World Trade Center at 8:46 a.m. United Airlines Flight 175 crashed into the South Tower at 9:03.
Time passed. At about 9:25 a.m., one of the pilots checked in with Cleveland. Ohio, traffic control, with a cheery "Good morningl"  
With the microphone still open to Cleveland, sud­denly the air-traffic controller could hear the sound of screaming and scuffling over the open microphone. It was 9:28 a.m.

U.S. Rep. John P. Murtha, D-Johnstown, a ranking Democrat on the Defense Appropriations Subcommittee, described the announcement this way: "As they got toward Cleveland, the hijackers said 'Look, just be calm, we're going to land this plane.' "
By that time, though, Jarrah and his crew apparently had already drawn blood.

Near Cleveland, about 125 miles from Pittsburgh, the westbound Boeing 757 had made a sudden turn at 9:37 a.m., looping back to the southeast at 500 mph. It was flying erratically at an unauthorized altitude. Air traffic controllers suddenly lost radio communication with the aircraft. As it turned out, Flight 93 passed almost directly over Pittsburgh as officials were scrambling for answers.
Full, who was at the county's emergency operation center in Point Breeze, received word of the stray flight from Brad Penrod, chief operating officer at Pittsburgh International Airport.
"I've been pretty much on the cutting edge of most of the terrorism planning in the region for a number of years," Full said. "I had participated in a lot of drills and exercises and a lot of wild scenarios of what a terrorist attack would look like. Never had we used the concept of passenger planes being used as cruise missiles against us."
Air traffic control had alerted Penrod as soon as Flight 93 stopped communicating.
"They were making the assumption that it was hijacked," he said.
Almost immediately, the FAA ordered the tower evacuated at Pittsburgh International.

- FBI and Justice Department officials have told the Globe they do not believe any of the hijackers were jumpseating on Sept. 11,
- United will not explain why, but the plane was delayed on the ground and didn't take off until 8:42
- As it flew west over Pennsylvania and into northern Ohio, United transmitted a systemwide message, warning its pilots of a potential "cockpit intrusion."
  The crew on Flight 93 replied by pushing a button that read out, "Confirmed."
- Authorities suspect the plane was hijacked about 40 minutes into its flight.
- As with Flight 77, the hijackers claimed they were taking the plane to another airport.
  "Hi, this is the captain," said Jarrah, according to a tape of an apparent inadvertant radio transmission obtained by ABC News. "We'd like you all to remain seated. There is a bomb on board. And we are going to turn back to the airport. And they had our demands, so please remain quiet."

When Jefferson gets on the line at 9:45 a.m., she immediately begins interviewing Beamer. “What is your flight number? What is the situation? Where are the crew members?”
        Beamer tells Jefferson that one passenger is dead. He doesn’t know about the pilots. One hijacker is in the rear of the plane, claiming to have a bomb strapped to his body. The conversation is urgent, but calm. Then Beamer says, “Oh my God, I think we’re going down.” Then adds, “No, we’re just turning.” At this point, investigators theorize, one of the hijackers was flying erratically. The plane plunges from its assigned altitude and the transponder is turned off.

The phone rang. It was her husband, Tom; and he sounded odd. "Are you okay?" She asked. "No," he said, speaking quickly and in a low voice. "I'm on a plane. It's United Flight 93, and we've been hijacked. They've knifed a guy, and there's a bomb on board. Call the authori­ties, Deena." Then he hung up quickly so she could make that call.
At about 9:45, Deena was on the phone With the FBI when she heard her call-waiting beep. It was Tom again. "They're in the cockpit now,"e, Deena had heard that a plane had crashed into the Pentagon, and she was sure it was Tom's.

 Shortly before 9:45 a.m., the phone rang. It was Jeremy Glick, calling from Flight 93
For several minutes, they told one another of their love.
What was this about a World Trade Center at­tack? He wondered aloud, "Is that where we're going, too, or are they just going to blow it up?" She told him there was nothing left of the Trade Center to crash into. She asked if the hijackers had guns. "No machine guns, just knives," Jeremy replied.

9:49 a.m. The FAA orders the Pittsburgh control tower evacuated. Shortly before, Cleveland flight controllers called Pittsburgh flight control and said a plane was heading toward Pittsburgh and refusing to communicate

John P. Joyce, now the acting special agent in charge of the Pittsburgh FBI, was assistant special agent in charge of counter-terrorism on Sept. 11. In a recent interview, Joyce said he didn't learn about a problem with Flight 93 until he heard it had crashed.
"I got a telephone call from (Pittsburgh Deputy Police Chief) Charlie Moffatt. He was considering whether to evacuate the Downtown high-rise office buildings," Joyce said. "I told him, 'Look, we don't have any intelligence indicating any of these planes are going to be directed toward a building in Pittsburgh, so I don't really have an justification to provide to you to evacuate the buildings, but if you guys decide that's what to do, that will be your decision."
"One person put their hand up, 'I have information the plane has crashed,' or, 'I have information there is another plane that just hit the Department of State building in D.C., which turned out to be false. Then the information just got really bizarre," Rowntree said.
Roddey also considered ordering an evacuation even at the risk of tweaking the mayor.

Sometime shortly before 10 a.m., the direct line from Cleveland Air Traffic Control rang inside the control tower at Johnstown-Cambria County Airport, 70 miles east of Pittsburgh.
Did Johnstown tower have any radio contact with a large aircraft about 20 miles to its south? Supervisor Dennis Fritz and controller Thomas Hull picked up binoculars -- the tower has no radar -- and scanned the horizon to the south. The day was clear and, from the highest point in the area, they could spot radio towers in neighboring Somerset County. A large plane would have stood out. "We didn't see a thing," Fritz said.
Hull went on the radio and broadcast an open message: "Aircraft 20 South of the field, contact Johnstown tower ... ."
Ninety seconds later, Cleveland called back. The plane was now 15 miles south and heading directly for the Johnstown tower.
"We suggest you evacuate," they told him.
Fritz ordered trainees and custodial staff out of the 85-foot tower. He and Hull stayed at their posts and scanned the south with binoculars. It occurred to Fritz that the plane must be flying below the level of the mountain ridges around them.

From the back of Flight 93, CeeCee Lyles finally reached her husband, Lorne.
"Babe, my plane's been hijacked," she said.
snip..
Forty-five seconds after telling Fritz to evacuate the Johnstown tower, Cleveland Air Traffic Control phoned again.
"They said to disregard. The aircraft had turned to the south and they lost radar contact with him."
It was 10:06 a.m.
Fritz and Hull studied the horizon to the south. They couldn't see a thing.


--
Pennsylvania Rep. John P. Murtha, the ranking Democrat on the House Appropriations defense subcommittee, said at the crash site near Shanksville, Pa., yesterday that he believes a struggle took place in the plane's cockpit. He added that he believes the plane was headed for a significant target in Washington.
"There had to have been a struggle, and someone heroically kept the plane from heading to Washington," Murtha said.
Whoever was ultimately in control of the plane, Flight 93 made a number of odd maneuvers in midair before it finally plunged to earth. "Halfway through its trip, around Weston, W.Va., it took some sharp turns, all within about two or three minutes," said Jeff Krawczyk, chief executive of Flight Explorer, a software firm that uses Federal Aviation Administration data to track flights.
"It was going west, then took a turn to the north, and then went west again," Krawczyk said. Then the plane headed toward Kentucky and took a sharp turn south toward Washington, and around that time the FAA center in Cleveland lost contact with the flight, apparently because someone on board had turned off its transponder, he said.
Brad Clemenson, a spokesman for Murtha, said the aircraft apparently made at least two other sharp turns during its last minutes -- swerves that are detectable in Flight Explorer's computerized reconstruction of the jet's path.
Dennis Fritz, director of the municipal airport in Johnstown, Pa., said the FAA called him several times as the plane approached his city, and even warned him to evacuate the tower for fear the jet was going to plow into it.
"They said the plane was very suspicious, and they didn't know what it was doing," Fritz said. Flight 93 crashed into a field 14 miles south of Johnstown. (wash post 9/13/01)

Thursday, September 13, 2001
By Jonathan D. Silver, Post-Gazette Staff Writer
No one can yet say exactly how close the hijacked jetliner that crashed Tuesday in Somerset County came to Pittsburgh, but a map of the flight path shows the plane passing just south of the city.
The Federal Aviation Administration said yesterday it turned over to the FBI a radar record of United Airlines Flight 93's route.
The data traced the Boeing 757-200 from its takeoff from Newark, N.J., to its violent end at 10:06 a.m., just outside Shanksville, about 80 miles southeast of Pittsburgh.
FBI agents refused to comment about the flight path.
"People are asking, 'Was there danger to Pittsburgh?' It's really too early, in my view, to comment on that," said Jeff Killeen, a spokesman for the FBI's bureau in Pittsburgh. "We want to speak with one voice, and only when we're perfectly ready to. Information control is critical to this investigation, and we're not commenting on the flight path at this time, and we're not commenting on a number of issues, like what may have been said in the cabin."
Local emergency management and airport officials spoke freely about what they were told of the plane's location.
But the details relayed to them during a tense morning that had already seen three terrorist-driven plane crashes in New York and Washington, D.C., were sparse, giving them little idea of where the fuel-laden jetliner was coming from or where it was going.
During the two hours Flight 93 was aloft, it traveled westward to Cleveland, then made a sharp turn to the south, according to a map provided by Flight Explorer, a Virginia company that sells real-time flight data it receives from the FAA.
Flight Explorer's map shows that after the jetliner turned south, it banked back eastward, cutting through West Virginia's Northern Panhandle before re-entering Pennsylvania.
A series of air traffic controllers would have handed off the plane several times, moving from Newark to New York to the FAA's Cleveland Air Route Traffic Control Center as the plane headed across the country.
Shortly after the second plane crashed into the World Trade Center at 9:03 a.m., Allegheny County Emergency Services Chief Robert Full called Bradley Penrod, deputy director of the Allegheny County Airport Authority, about the situation.
They chatted, exchanged phone numbers and hung up.
About 10 minutes later, Full's phone rang. It was Kurt Sopp, the airport authority's security manager.
Full said Sopp told him that he had been informed by Pittsburgh International Airport's air traffic control tower "that there was a plane within 10 miles in the Pittsburgh airspace that they had no contact with whatsoever, and they had reason to believe it was possibly a hijacked aircraft, and they were taking appropriate action by moving personnel out of the control tower."
Airspace is generally considered to be a 20- to 30-mile radius from an airport.
That was all Full learned of the plane. He had no idea of its altitude, heading, speed or apparent destination.
"It meant to me that it was pretty damn close to the airport, especially when they told me the control tower was beginning to move personnel out of the tower," Full said. "I didn't ask for any of those particulars. I didn't even look at the clock for a time."
Full got off the phone with Sopp and alerted Pittsburgh officials. Full alerted City Communications Chief John Rowntree. But even as Rowntree was learning about the mysterious plane, it continued on its southeast path, away from Allegheny County.
As the plane neared Somerset County, air traffic controllers in Cleveland alerted their counterparts at John P. Murtha Johnstown-Cambria County Airport that a plane was about 12 miles away, "heading directly at the airport at about 6,000 feet," said Joe McKelvey, the airport's executive director.
"The Johnstown tower chief told me that under the circumstances, he was going to evacuate the tower," McKelvey said. "Before either one of us could get off the phone, the aircraft had already passed us by."

cockpit doors..
"Although (b] the cockpit door remained locked during flight, it provided only flimsy protection on September 11. The door was designed to withstand no more than one hundred and fifty pounds of pressure , so that it could be forced open in emergencies, allowing the pilots to escape outward or passengers to escape inward to climb out of a cockpit window. A heavy shoulder would dislodge the door."
(p. 8)

(email to author)
Problem would be if you push this door very hard and it opens you are in no good attacking position as you will fall down on the floor or have to regain your balance at least. No chance that you can kill the pilot before he even had the chance to turn around.
And as far as I can recall no phone call of the passengers speak of hijackers pushing violently the door open. But I'll have to countercheck this.

Spooked 911:
This tells us:
1) that the crew locked the cockpit doors, so the hijackers could not have just walked in, they would have to smash the door open.
2) the pilots can hear knocks on the cokpit door. If they can hear knocks, they can hear someone trying to ram open the cockpit door.
3) the crew members were prepared for a hijacking!

"Dahl and Welsh had established the secret-knock sequence that she would use to enter the cockpit. The code was changed on every flight. United flight attendants did not carry cockpit keys, which were to be used for emergencies. One key was always located in the forward part of each aircraft, sometimes in the galley, but not always in the same place"
(p. 8)
"In the event of a hijacking, flight attendants were to phone the cockpit and mention the word "trip".
(p.9)

-----------

Beamer told Jefferson that the pilot and copilot apparently were dead and the hijackers were flying the plane. He said one hijacker was guarding 27 passengers in the back of the plane with what appeared to be a bomb tied around his waist.
He said two more hijackers were in the cockpit, while the fourth was guarding the first-class cabin.
http://www.boston.com/news/packages/underattack/news/planes_reconstruction.htm


----------
The four hijacked planes were all Boeing aircraft, and every one of the company's planes has a standard cockpit key, the so-called Boeing key. Perhaps the hijackers grabbed the key off one of the wounded flight attendants and barged into the cockpit. Perhaps they already had copied the key, having studied Boeing flight manuals and taken simulator rides in Boeing aircraft. Perhaps they opened the door with a box cutter to the neck of one of the flight attendants.
A flight attendant's body was found at one of the crash scenes with thin wire bound tightly near her manicured hand.

BTS...
http://www.thoughtcrimenews.com/flight93notscheduled.htm
by Simon Aronowitz of "ThoughtCrimeNews.com"
The Director of Public Affairs for the Bureau for Transportation Statistics confirmed that the database should list all domestic United [or American, or any other domestic line. DL.] flights. In a telephone interview, Dave Smallen explained that the statistics are compiled from reports submitted by the airlines rather than generated automatically by air traffic control (ATC) computer systems. Smallen stated that missing statistics would be pursued, and that with regard to details of flights from the main carriers including United, "Everything should be filed".

Additionally, Smallen explained that even if a flight crashed or had to conduct an emergency landing, it would still be listed in the database with its departure time. An emergency landing would be denoted in the statistics as a `diversion'.
The figure for the number of diversions listed for UA93 on 9-11 suggests that there may be a lack of data integrity in the BTS databases [Simon is referring here to possible lack of integrity in the SUMMARY stats. DL.]. However Smallen's explanation of how the information is submitted and handled suggests that the Bureau for Transportation Statistics would endeavour to keep its data accurate. Flight 93 is now one of the most renowned flights in modern history, yet the government data on this flight suggests that all was not as it seemed.
[excerpt from: http://www.thoughtcrimenews.com/flight93notscheduled.htm, and article primarily about UA93, but with the above important information from Dave Smallen, Director of Public Affairs for the BTS, about the source for BTS data, and how they are handled, with respect to "diverted" flights.  He states, "even if a flight crashed or had to conduct an emergency landing [as purportedly happened in the cases of AA11 and AA77], it would still be listed in the database with its departure time."  Which is as we have suspected all along, based on the data present for other flights that failed to arrive at their destinations.]


Also, from D. Lemmon
A couple of weeks ago I was checking the BTS data to see what it contained about UA93 and UA175 for the days immediately after 9/11.  I found that both those flights are missing from the database beginning 9/12/01 and continuing at least through the end of September.  I sent Gerard an e-mail about this, and his reply is immediately below this note.  Below both messages are the BTS data for all LAX-bound flights out of BOS and SFO-bound flights out of EWR for 9/9 through 9/30.  

[Reply 4/27 from Gerard Holmgren to D. Lemmon...]
I hadn't noticed that before. I didn't back up any post S11 data, so I can't say whether they've since changed it. We should assume that it's not doctored. If it is, then that in itself is suss.
The flights should be in there. They were daily flights as I understand it.
The BTS reporting regulations are that any flight for which a computerized reservation system is initiated, must be reported unless the flight is cancelled more than 7 days prior to the scheduled departure date.
So as this data stands, they either never scheduled any 93s or 175s after S11, indicating foreknowledge, or else if they ever were scheduled, then they cancelled them with at least 7 days foreknowledge of what was to come.

From: D. Lemmon
To: Gerard Holmgren
Subject: Possible UA93, UA175 Anomaly?
Gerard,
I don't know if this information is already old ground, or whether it has much significance, but it seems interesting, and I thought you might want to know about it.
From the BTS On-Time Detailed Statistics > Departure Statistics database...
For at least several days following 9/11, flights UA93 and UA175, which allegedly crashed into WTC2 at 9:03 AM and into the reclaimed Pennsylvania strip coal mine at 10:06, respectively, do not appear in the BTS data.  There are no records for them, as there were no records for AA11 and AA77 on 9/11, as you discovered in November, 2003.
In the cases of AA11 and AA77, BTS records ARE present for both flights for the dates immediately before and after 9/11. (And, of course, the database now (since November/December, 2004) includes records for both those flights, but, significantly, without Actual Departure Times, Wheels-Off Times, or Tail Numbers.)
When the BTS Departure Statistics for BOS and EWR are sorted by Destination Airport, a regular pattern of flight numbers (odd-numbered denoting Westbound flights) bound for LAX and SFO, respectively, emerges.   
At Boston, the flight numbers 51, 169, 175, 177 recur regularly from 9/5 through 9/11 without deviation.  For 9/12 through 9/15, the pattern is the same, except that UA175 is absent on each of those dates.  Thus, the pattern of LAX-bound flight numbers from 9/12 through 9/15 is 51, 169, 177, without deviation.
At Newark, the flight numbers 75, 77, 79, 81, 91, 93 recur regularly from 9/5 through 9/11, except that UA77 is not present for 9/8.  For 9/12 through 9/15, the pattern is the same, except that UA93 is absent on each of those dates.  Thus, the pattern of SFO-bound flight numbers from 9/12 through 9/15 is 75, 77, 79, 81, 91. Also, UA77 is absent for 9/15. Maybe United didn't fly UA77 on Saturdays. [Please note that I have now extended the tables for both BOS and EWR to show the related data through the end of September. After 9/15, flights UA165 and UA143 were added at BOS and late in the month, Flights 73, 81, and 91 are present and absent for some dates at EWR, presumably in keeping with normal operations.  But the sudden, permanent disappearance of UA93 and UA175 from the database beginning precisely on 9/12 require an explanation.  Based on Gerard's discussion of how the database is set up, with a seven-day rule on any changes, their absence points to either a rare coincidence, especially since TWO flights at TWO airports are involved, or to foreknowledge. D. 5-3-05]
I am presuming that the BTS database is built with "skeleton" records, entered for all flights several days or weeks in advance of the actual flights, based on the airlines' schedules as soon as they become known, to be updated when (or shortly after) flight events (Departure, Wheels-Off, Arrival, etc.) actually occur.  If that is the case, then it would seem strange that both UA93 and UA175, the very flights involved in two of the four 9/11 "hijackings," suddenly stopped being regularly-scheduled flights on United Airlines' schedule, and so stopped appearing in the BTS data, beginning precisely on September 12, 2001.  Of course, that would imply either that it was known in advance of 9/11 that UA93 and UA175 would not exist after that date, or that a real coincidence occurred.
I do not recall noticing this before, and I'm checking my archives to see whether I saved any actual BTS data for UA93 and UA175, for dates AFTER 9/11, from the database as it stood in 2003 or earlier, and as I had done for AA11 and AA77 right after your discovery.

The fuselage burrowed straight into the earth so forcefully that one of the "black boxes" was recovered at a depth of 25 feet under the ground.

Miller was among the very first to arrive after 10:06 on the magnificently sunny morning of September 11. He was stunned at how small the smoking crater looked, he says, "like someone took a scrap truck, dug a 10-foot ditch and dumped all this trash into it." Once he was able to absorb the scene, Miller says, "I stopped being coroner after about 20 minutes, because there were no bodies there.
  snip...
 Immediately after the crash, the seeming absence of human remains led the mind of coroner Wally Miller to a surreal fantasy: that Flight 93 had somehow stopped in mid-flight and discharged all of its passengers before crashing. "There was just nothing visible," he says. "It was the strangest feeling." It would be nearly an hour before Miller came upon his first trace of a body part. The emotionally wrenching impact of what happened to the bodies caused Miller to resolve to seek out and talk personally to every one of the victims' families

Five months after the crash, once the long, painstaking identification process was completed, he realized he had one larger duty remaining. Finally, some fragment of each of the dead had been positively identified, either by DNA or, in a few cases, fingerprints
