No I don't. Even if they came out with a bunch of videos people would say they were doctored videos.
I mean the black box from the flight was recovered along with dna from all but one of the passengers, how is THAT not proof. The only way to say it is not proof is to believe that hundreds of people that were at the scene that responded/ cleaned it up/investigated it were all in on it. I don't believe they were all in on it. I don't believe the plane parts were planted. I don't believe the over a hundred witnesses that saw the plane fly into the Pentagon are lying or in on it. But yet other people do, so no I don't think there is anything at all they could do to put it completely to rest and end all speculation.
