Keep in mind as well that airspeed would be critical for maximum effect.

Moving too fast, the plane flies right through the building, certainly 
causing massive damage and almost certainly starting a fire.  However, 
that's not optimal.

Fly too slowly, and you're on the edge of a stall - no laughing matter in 
any aircraft, but especially critical in these cases, due to the maneuvers 
every aircraft performed.  Also, fly too slowly, you might not completely 
penetrate the building.

 From the beginning, there's been no doubt that the pilots were type-rated 
on the Boeing 757/767, nor has there ever been any doubt, at least in my 
mind, that these were not American or United pilots... with the possible 
exception of the United flight that crashed in PA.
