9/11: The official account of Flight 77 defies the laws of science

"The official account of Flight 77 on September 11, 2001 defies the laws of science," says Mr. Enver Masud — an engineer.

Calculations based on its Flight Data Recorder (FDR), prove that American Airlines Flight 77 could not have struck the Pentagon in the manner described in official reports.

Given the topography, and the flight path defined by the FDR data provided by the National Transportation Safety Board (NTSB), anyone competent in geometry and physics can calculate the force exerted on “Flight 77” when it would have to transition from its downward path to level flight prior to striking the Pentagon.

Reconstructing Flight 77’s path from the FDR data is not a trivial exercise. It requires expensive software, and details of the topography below the alleged flight path. Pilots for 9/11 acquired the software, and painstakingly drew the topography to simulate “Flight 77’s” path.

From the flight path information provided by Pilots for 9/11 Truth, we calculate a downward force on “Flight 77” of 33 times the force of gravity, i.e. 33 Gs, when the aircraft would have to transition from its downward path to level flight about 200 yards in front of the Pentagon.

The Boeing 757 would act as if it had increased its weight by 8,276,850 lbs, or 32 times its normal weight.

Flight 77 could not possibly survive this G-Force.

Had Flight 77 attempted this maneuver, it would have crashed on the lawn in front of the Pentagon — the pilot would not have been any condition to fly with "the top of the fuselage of the aircraft no more than 20 ft above the ground" (Pentagon Building Performance Report, p14).

Therefore, Flight 77 could not be the object seen flying level across the Pentagon lawn at "530 miles per hour" (The 9/11 Commission Report, p10) in the Pentagon security camera film.

This single fact — the G-Force on “Flight 77” — is sufficient to refute the official account of Flight 77.
