oh, come on!
hundreds of tons of debris and building laying
down thousands of tons of impact force after falling that far
wont bend steel? even 2 inch diameter #8 bolts and those monsterous rivets
they used would give out under that kind of onslaught.

HAPPENED ON SEPT 11
Hi Joe and All,
I really don´t want to believe this. That´s part of the problem. But the
buildings fell unusually fast, from film and stopwatch just about at freefall
speeds. I would have thought if most of the structural steel was okay, except
for the areas where the fires were, wouldn´t they have slowed the
descent?

That's a very good point Kirk. I wonder how do the civil
engineers deal with that bit?
Andrew?

To fall straight down means the failures supposedly caused by heat

the failed side and then forces cause more failures. It is a very tricky
business making them fall straight down.

I
studied Civil Engineering with a major in Structures and Analysis not
Medicine with a major in Psychiatry so I'll leave the reader to make
their own judgements on the rest of this.
