This is thought to be the same security video that Doubletree employees watched in "shock and horror" over and over again before the FBI came and confiscated it reportedly the next day:?A security camera atop a hotel close to the Pentagon may have captured dramatic footage of the hijacked Boeing 757 airliner as it slammed into the western wall of the Pentagon. Hotel employees sat watching the film in shock and horror several times before the FBI confiscated the video as part of its investigation.? - Inside the Ring/Gertz File (09/21/01)
As one blogger put it, "Let's face it: five years of work can get you pretty danged impressive CGI". We shall see, I hope.
