A person using the pseudonym Elizabeth Nelson told The Project Camelot website that she personally heard officials agree on the order to shoot down Flight 93. The decision was apparently made because the plane was flying in a no-fly zone near to Camp David and heading toward Site R, a military facility in known as the “backup Pentagon”.
Because the woman refuses to provide her real name, the authenticity of her story is very much up for debate, but in a 40 minute MP3 recording (click here to listen) of the interview, she relates what she witnessed in as sincere and genuine a way as one could expect. This individual has seemingly little to gain from making up such a story, unless it’s part of a deliberate disinformation campaign.
It may well be the latter since the current working hypothesis for the shoot down of Flight 93 is that the passengers and crew had succeeded in regaining control of the aircraft and had they landed, the reality on the plane would not have matched the cover story and the whole 9-11 cover story would have collapsed.
