You sure haven't been paying attention. The Pentagon surveilance tapes were released under a FOI motion. They showed (surprise!) an airplane crashing into the building.
We weren't "told" how things happen. We saw them happening on our television sets, listened to eye witnesses, and otherwise acted logically and sanely.
I deliberately didn't answer that question. A typical 9/11 nutbar's questions contain either an unfounded accusation or an outright lie.
To answer that question in any way would be to agree that there were "tapes held back" (which I don't know any more than they do), and it wouldn't matter what was released anyway. The mere existence of a high-resolution tape would feed into the "foreknowledge" fantasy. I an hear it already---how would they have known to stand in a certain spot and film everything just right, if they hadn't KNOWN AHEAD OF TIME that a missile disguised as a plane was coming in at a preset time?
How much did you see?.....a split second of the final impact?
Just have them show all of the confiscated tapes and we can move on.
