Produced in 2004 by the National Transportation Safety Board (NTSB) for the National Commission on Terrorist Attacks Upon the United States (also known as the 9-11 Commission). Commission staff attended a playback in the NTSB's Vehicle Recorders Division laboratory on April 22, 2004. That presentation was not very convincing. I nevertheless believe that the document should not be deleted from the public memory.

Disclaimer : This video is for general education and entertainment purposes only. The animation contains various inaccuracies. Viewers should not draw conclusions regarding the outcome of the event. Recipients, who requested this animation via FOIA request, have been advised of its nature as a "working copy", not for official purposes.

On a personal note : I am convinced that the NTSB experts are highly skilled aviation professionals who exactly knew what they were doing. Also, a FDR does not record any audio. I decided not to dub the video with ATC audio, even if it made the watching experience more interesting, since that would mean tampering with evidence.

Dedicated to the lives lost on September 11, 2001. May they rest in Peace.
