The evidence shows that Flight 93 did indeed crash near Shanksville, and suggests that the passengers did struggle to gain control of the plane. However, the cause of the crash was apparently trauma to the aircraft -- such as a missile strike -- rather than the actions of whoever was in the cockpit. Evidence of such trauma preceding the jetliner's nose-dive includes the widely scattered debris field, numerous ear- and eyewitness accounts, and evidence that NORAD and the 9/11 Commission changed the timeline to hide the plane's true fate.

 Far-Flung Debris

Local officials stated that crash debris was spread over a wide area. According to the Pittsburg Post-Gazette, state police Major Lyle Szupinka "confirmed that debris from the plane had turned up in relatively far-flung sites, including the residential area of Indian Lake." The residential areas of Indian Lake range from three to six miles from the crash site. As noted on the pages describing Flight 93 and its crash site, there were a number of debris fields. Small debris descended over Indian Lake and New Baltimore, about three and eight miles from the primary crash site, and an engine core was separated from the main impact crater by about 2000 feet.

 Some officials have suggested that wind scattered the debris once on the ground, but the wind certainly couldn't have blown a one-ton engine a half-mile, nor could the 9-mile-per-hour wind have blown debris for eight miles.

An article in Popular Mechanics attempts to explain the far-flung debris by suggesting that the engine "tumbl[ed] across the ground" and that the light debris was "blasted skyward by the heat of the explosion from the crash." Such scenarios are impossible given the nature of the crash, wherein the plane dove into the soft ground from a nearly vertical trajectory. This is evident in the deep impact crater whose shape mimics the cross-section of the aircraft, and by the agreement among eyewitnesses that the plane dropped from the sky in a vertical fashion.

 Struck in the Air

 Eyewitness accounts corroborate physical evidence that portions of the plane were destroyed in the air, consistent with a missile strike from a nearby military plane. These accounts support the following elements.

• A white jet in pursuit of the jetliner
• Peculiar engine sounds before the crash
• Sounds of explosions before the plane fell from the sky
• Appearances that the plane suddenly began to drop vertically

Further evidence that Flight 93 was shot down was provided by an apparent slip-up by Secretary of Defense Donald Rumsfeld In a candid moment in front of U.S. troops, Donald Rumsfeld strays from the official story of heroic passengers flying fight 93 into the ground by saying it was "shot down."  

See the video below where Rumsfeld slips up and said the plane was shot down!

I think all of us have a sense if we imagine the kind of world we would face if the people who bombed the mess hall in Mosul, the people who did the bombing in Spain, or the people who attacked the United States in New York, shot down the plane over Pennsylvania and attacked the Pentagon, the people who cut off peoples' heads on television to intimidate, to frighten -- indeed the word 'terrorized' is just that. Its purpose is to terrorize, to alter behavior, to make people be something other than that which they want to be.

Fudging the Timeline

There are several independent lines of evidence that establish that Flight 93 crashed at 10:06 in Shanksville, PA. These include the following:

• Seismic signals were recorded by seismic observatories at Soldier's Delight, MD, and Millersville, PA, which pegged the impact time at 10:06:05, with an error margin of 5 seconds.
• A report from Cleveland Air Traffic Control that they had lost radar contact with Flight 93 at 10:06.
• Reports by witnesses on the ground of the plane flying low and erratically around 10:05.
• Various press reports put the time at 10:06.

• Radar records were released by the FAA. The Post-Gazette noted, two days after the attack:

  The Federal Aviation Administration said yesterday it turned over to the FBI a radar record of United Airlines Flight 93's route. 
  
  The data tracked 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. 

Despite these extensive bodies of credible evidence establishing Flight 93's impact time at 10:06 AM, NORAD and the 9/11 Commission asserted that the impact was at 10:03. NORAD provides no evidence to back up its claim, but the Commission provides a long footnote to justify its use of 10:03.

United Airlines Flight 93 was the plane that crashed in Pennsylvania, short of its alleged target, the Capital. The widespread debris field from the crash, together with eyewitness reports, strongly suggest that the jetliner was shot down by a missile fired by a pursuing jet. Flight 93 was a Boeing 757-200 on a scheduled flight from Newark to San Francisco, with 38 passengers, five flight attendants, and two pilots.

Course

At 8:42 AM, Flight 93 took off from Newark International Airport, 41 minutes after its scheduled departure time. According to NORAD's September 18th timeline, at 9:16, the FAA informed NORAD that the flight may have been hijacked. Several communications with air traffic controllers indicate that Flight 93 was hijacked at around 9:27. At 9:30, the transponder signal ceased. At about this time, the plane apparently reversed direction and began flying toward the capital.

Phone Calls

There were numerous calls allegedly from Flight 93, most of them made using cell phones, and being relatively short. An exception was the call from passenger Todd Beamer on an Airfone, which was routed to Verizon supervisor Lisa Jefferson. Jefferson interviewed Beamer in detail in a conversation that would last from 9:45 until his famous last words before leading a passenger revolt: "Let's Roll".

The AP reported that at 9:58 a frantic passenger called from a bathroom and told operator Glenn Cramer that he had seen an explosion and smoke and that the plane was "going down". Investigators believe the passenger was Edward Felt.

Crash

At 10:06 AM, Flight 93 was apparently shot down near Somerset, PA. The official story that it was flown into the ground as a result of a struggle to control the cockpit is contradicted by the reports of eyewitnesses on the ground, as well as the phone call attributed to Edward Felt.

The crash site, in a reclaimed strip mine, comprised a central debris field and several smaller debris fields some distance away. One of the engines was found over half a mile away from the main field. Other debris fields were found 2, 3, and 8 miles away. This evidence is virtually impossible to reconcile with the official story.
