This was an obvious error. I wanted to say, that there were 40 m above 
the impact zone, not 40 floors.

But this number seem s a little too small and the are had been more 
meters of the upper floors. (will try to find out the correct numbers).

5% is too much. But - unfortunately - I don't have the correct numbers. 
Maybe this area ( you would get, that is steel only, if you make an 
imaginary cut through the building) is less then 5% of the entire floor 
area.

Sorry, but I don't know this figure. 5% was a rough guess.

In any case, this is only a demonstration about how such a calculation 
could be made, not a proper calculation.

This is an own profession (calculation of the steel frames for 
skyscrapers). But certainly there are a few of these professionals, who 
could actually make such a calculation.

In any case: the steel frame of the WTC-towers seemed to be more than 
sufficient to keep the buildings upright.
