the security camera photos WERE released...I saw them on TV soon after the crash...but they showed nothing because the plane was going so fast, it passed BETWEEN frames of the camera. The security camera was not a video, but an every-few-seconds set of snapshots. It showed nothing, then a fireball, which led conspiricy buffs to claim the explosion happened beside the building...though they had no idea how, or what happened to the missing plane!

"we got a hole in a building, and our jetliner ain't anywhere else, we are just guessin' we know what happened, especially with little airplane pieces scattered around"
