hmmm. I assume drug means dragged - yet I cannot see a single sign of any wing being dug into the ground just before the aircraft hit the building at however many hundreds of miles an hour.
Doesnt look like a blade of grass was damaged in fact.
Plus, for one wing to dig into the ground the aircraft would have to be much higher up than it was, it hit virtually at ground level.
Well, he was there. You on the other hand, are just someone on the internet. So of course you're right.
