Though it's quite difficult for people to imagine what happens to a plane in a crash, it's entirely possible for a plane to be fully absorbed into a building.
You don't see many plane crashes, but the ones you do are generally ones that have crashed into the gound and not at a 90 degree angle to a wall / building, where the concentration of impact and explosion will be magnified somewhat. Therefore as the whole thing is collapsing inwards and into the building, the wings will kind of try wrapping backwards, though would still wonder how the engines get into the factor myself. Remember what planes are made from, aluiminium, and that'll melt at rather low temperatures, though not all or everything would melt, just some bits would probably deform quite a lot. Unless you have some sort of ultra computer simulation of what would happen to a plane in those circumstances, people aren't going to believe much, or a decent video of it to at least stop the conspiracy theories.
I've not seen any of the new vids, as they don't seem to be on the web at least. Just hoping it spreads a little more light on it, with more than just a couple of freeze frames.
awesome job
