We have had some concerned that the detailed information already presented in our films, on our website, and numerous papers written on our forums wasn't thorough enough and that some wanted a "Technical Paper" outlining our findings. For those who have reviewed our work, this will be redundant. Thank you for your understanding.

Pilots for 9/11 Truth, an international organization of pilots and aviation professionals, petitioned the National Transportation and Safety Board (NTSB) via the Freedom of Information Act to obtain their 2002 report, "Flight Path Study-American Airlines Flight 77", consisting of a Comma Separated Value (CSV) file and Flight Path Animation, allegedly derived from Flight 77's Flight Data Recorder (FDR). The data provided by the NTSB contradict the 9/11 Commission Report in several significant ways:

- The NTSB Flight Path Animation approach path and altitude does not support official events.

  • CSV file and animation as plotted and provided by the NTSB through the Freedom Of Information Act (1) at time stamp 09:37:44, reports pressure altitude as 173 (csv file) and 180 feet (animation). When adjusted for local pressure to true altitude, the aircraft is ~473 and ~ 480 feet above sea level, respectively. Too high to hit the light poles as reported being struck on Washington Blvd and the Pentagon if trends are continued. NTSB calculates and reports impact time of 09:37:45 in their NTSB Flight Path Study (2).
  • The Animation Reconstruction as plotted and provided by the NTSB shows a flight path north of the required physical damage path. (1)

- All Altitude data shows the aircraft at least 300 feet too high to have struck the light poles.

  • See description above. Light pole height is ~ 80 feet above sea level for tallest pole. (USGS Ground Elevation ~ 40 + Pole Height 40, Virginia Dept of Transportation)

- The rate of descent data is in direct conflict with the aircraft being able to impact the light poles and be captured in the Dept of Defense "5 Frames" video of an object traveling nearly parallel with the Pentagon lawn.  

  • Rate of Descent is in excess of 4,600 fpm (3). Aircraft height at 09:37:44 is ~473' above sea level. Pentagon Height is 110' above sea level. 473 - 110 = 363. 363 fps x 60 = 21,780 fpm descent required for last second to hit top of pentagon. 21,780 fpm descent rate for one second. This represents a 24.928 degree descent angle.

363/781 (distance based on 781 fps speed as reported by NTSB) = atan θ = .464788

θ = 24.928

24.928 degree descent angle is in direct conflict with the level approach as seen in the DoD "5 frames video" (4). Further, the aircraft would require a level approach considering the foundation doesn't show any signs of damage (5).

- The record of data stops at least one second prior to official impact time.  

  • Animation stops at 09:37:44. NTSB calculates impact time at 09:37:45. Many CSV file parameters terminate at 09:37:45.

- If data trends are continued, the aircraft altitude would have been at least 100 feet too high to have hit the Pentagon.

  • 4,600 fpm descent = 76.7 fps. Altitude at 09:37:44 as reported and plotted by NTSB when adjusted to local pressure indicates ~473(3). Impact time as reported by NTSB Flight Path Study is 09:37:45. 473 - 76.7 = 396. Top of pentagon height is 33 (ground elevation) + 77 (height of pentagon) = 110. 396 - 110 = 286.3 feet too high above the pentagon. Margin for error given as 186.3 feet due to altitude not present at time calculated by the NTSB for impact.

In August, 2006, members of Pilots for 9/11 Truth received these documents from the NTSB and began a close analysis of the data they contain. After expert review and cross check, Pilots for 9/11 Truth has concluded that the information in these NTSB documents does not support, and in some instances factually contradicts, the official government position that American Airlines Flight 77 struck the Pentagon on the morning of September 11, 2001 .According to the 9/11 Commission Report, which relied heavily upon the NTSB Flight Path Study, American Airlines Flight 77 struck the Pentagon at 9:37:46 AM on the morning of September 11, 2001 .  However, the reported impact time according to the NTSB Flight Path Study is 09:37:45 . Also according to reports, American Airlines Flight 77 struck the Pentagon and by doing so, struck down 5 light poles on Highway 27 in its path to the west wall.

The information provided by the NTSB does not support the 9/11 Commission Report of American Airlines Flight 77 impact with the Pentagon.

Pilots for 9/11 Truth is committed to discovering the truth surrounding the events of September 11, 2001 . We have contacted both the NTSB and the FBI regarding these and other inconsistencies. To date, they have refused to comment on, correct, refute, retract or offer side-letters that might explain the discrepancies between what they claim are the data extracted from the FDR of AA Flight 77 and the official story alleging its crash into the Pentagon.As concerned citizens and professionals in the aviation industry, Pilots for 9/11 Truth asks, why have these discrepancies not been addressed by agencies within the United States Government? Why have they falsely represented their own data to the American people? Pilots for 9/11 Truth takes the position that an official government inquiry into these discrepancies is warranted and long overdue. We call upon our fellow citizens to write to their Congressional representatives to inform them of these discrepancies and call for an immediate investigation into this matter.
