But the 707 could carry a full cross-country load of fuel. The ESB can't
really be used as a comparison because the bomber weighed something like
25,000 pounds (also used gasoline as a fuel). Modern-day fighter planes
such as the F-14 or F-15 are larger than WW2 era bombers.
The Empire State Building was designed in the '20's, before modern stress
analysis and materials. The ESB is a grossly inefficient building, needing
to be a wedding cake to get up to its 1300' or so. There comes a point when
you can't make the bottom broad enough to support the weight of the
top. You couldn't bring down the ESB (or similarly constructed building)
except by mechanically destroying most of a plane (geometrical plane, not
air plane) through the tower.
Hyman Brown, the Trade Center's construction manager, said the towers were
destroyed in the only way imaginable. He speculated that flames, fueled by
thousands of gallons of aviation fuel, melted steel supports, causing the
collapse. "Prior to 7 o'clock this morning, I would have told you there's
no way you could bring that building down," Brown said. "What you don't
plan for is 24,000 gallons of jet fuel. As far as I know, it's never been
thought of."
