I agree that the leveling of the first building was odd. I'm not an
engineer, but the destruction from the crash *appeared* to be isolated
to the upper floors. Likewise, heat is going to travel upwards and
spread the fire to the upper floors faster - which is what appears to
have happened. There floors in between the area of destruction and the
bottom floors appeared to be sound - then the building spontaneously
collapsed. Very strange.
