This technical paper is a supplement to the video presentation "The North Flight Path: Aerodynamically Possible – Witness Compatible" and will serve to prove that a North Approach over the Naval Annex and north of the Citgo gas station is aerodynamically possible and consistent with witness statements. The analysis is based on USGS survey of the Arlington area using scale modeling of buildings, obstacles, elevation and overall witness statements who independently corroborate placement of an aircraft opposite the physical damage observed at the Pentagon on the 11^th of September 2001.

More than one flight path will be evaluated to show best and worst case scenarios taking witness statements into consideration.

Considerations for Calculations;

- Aircraft type is unknown

- Stall Speed impossible to determine as outlined in the film.

- "Bank Angle" analysis based on level flight.

- "Pull Out" analysis based on Bank Angle and vertical acceleration required in the vertical plane to clear all obstacles and be consistent with witness statements.

- Speed: Flight Data Recorder (FDR) information not available for airborne vehicle witnessed on North Approach. Exact speed is impossible to determine based on witness statements. Several speeds are offered in this analysis including that of the Flight Data Recorder information plotted by the NTSB for this segment of flight in which many parameters conflict with a Pentagon "Impact". When using FDR information as plotted by the NTSB it would be technically inaccurate to focus on one parameter and ignore the rest for such a segment. Therefore, the reader must also understand FDR altitude as plotted by the NTSB for this segment has to be taken into consideration which shows too high to hit the Pentagon^*. With that said, we will still demonstrate how even the highest and final FDR speed plotted by the NTSB at less than 1 second west of the pentagon wall, is still aerodynamically possible for the North Approach based on bank and G loading for conventional aircraft, as witnessed. All other speed data as plotted by the NTSB for this segment will lower aerodynamic requirements than those demonstrated in this paper utilizing final FDR speed.

I'M posting the tech paper to ATS. Is that OK with everybody?
