Lots of easter eggs in this interview. Silverstein etc... but listen to Trump's answer to the question asked at (5:14) about the integrity of the buildings...
"How could a plane, even a plane, even a 767 or 747 or whatever it might have been, how could it possibly go through this steel? I happen to think they not only had a plane, but had bombs that exploded almost simultaneously, because I just can't imagine anything being able to go through that wall..."
"It just seemed to me that, to do that kind of destruction, is even more than a big plane, because you're talking about taking out steel, the heaviest calibre steel that was used on a building. I mean these buildings were rock solid..."
Also worth noting the steel column vaporising at (2:03).
So true the shills really hate this video of a F4 Phantom just being pretty much vaporized when crashing into a concrete wall and there is no way a bigger jet is going to go through those massive steel beams.
F4 Phantom Crash test
I remember also Trump said he got to visit the site the day afterward and saw all the metal beams which had holes and slices in them which was the result of shaped charges and also those melted steel beams before they hauled it all away as quickly as they could.
