What do you think about this?

Old, and debunked on other sites, though i see they've made the intro more impressive.

An airplane composed largley of aluminium crashing into concrete at 500 MPH isn't gonna leave big chunks of metal lying around, only tiny shreds lying all over the place. The hole in the wall is simply the focal point of the inertia of the mass of most of the plane, the wings are simply too weak to make holes, they just get smashed into shreads and burn in the resulting fireball (yes, aluminium burns, very brightly infact).
