But would this also say, that because the topmost floors weren't
subject
to the gravity of floors above them, so that the top of the rubble
should
be more intact? And does the photographs of the rubble show that this
is
the case, at all? No, I don't think so, that we should see topmost
floors
with less damage, at the top of the rubble...

Yes that does puzzle me to be honest. The top most floors appear to have
completely disintegrated, mind they did fall a long way and were subjected
to a lot of rising heat.

But both collapses appeared to have been quite smooth and even and the fact
that some areas were clearly damaged more than others appears to have had no
effect on the way the buildings actually collapsed. That appears to
contravene the laws of physics. Generally speaking buildings don't fall in
such a controlled way other than in a controlled demolition.
