The empire state is also much smaller with less intrinsic weight in each
floor. It was also designed without the use of computers to trim out all of
the over engineering etc used in older structures.

Subject: Re: The WTC constructions
I'm no expert either. I recall hearing that sometime during or after WWII,
a B-25 bomber smashed into the Empire State Building, causing damage to the
floors adjacent to the impact, but leaving
the rest of the building intact. This smallish twin engine military plane
was much smaller than the Boeing 767 or 757's that smashed into the WTC
towers.
The fact that both of these planes had just taken off on transcontinental
flights, means that they were heavily laden with fuel. I heard today on one
of the news reports that fuel was flowing to
lower floors, spreading the fire quickly.
Undoubtedly the tremendous heat from these fires severely weakend the steel
girders in the building, causing them to buckle. Once the top 1/3 of the
buildings collapsed, the bottom 2/3's were
unable to withstand the strain.
regards,
frank
