During a recent "Discovery Channel" 9/11 anniversary broadcast, a U.S. Army Corps of Engineers scientist expresses puzzlement regarding circumstances of the discovery of the flight data recorder "black box" allegedly belonging to American Airlines flight 77 at the Pentagon.

 

The data file obtained from this same "black box" contains a time and date stamp pre-dating the discovery of the "black box" itself.

The National Transportation Safety Board also possesses no records establishing the positive identification of this same "black box" discovered just inside the Pentagon C Ring exit hole.

Questions remain about the creation of the Pentagon C Ring hole within which the "black box" for American Airlines flight 77 was located.

Explosions consistent with alternative theories regarding the creation of the Pentagon C Ring hole were recorded by local media on September 11, 2001.
