The B-25 that hit the Empire State Building weighed around 41,800 pounds
maximum takeoff weight, with a normal total load of 974 gallons aviation
The 767 that hit the WTC has a maximum take-off weight of 412,000 pounds
and a normal total fuel load of 23,980 gallons aviation kerosine.
Roughly 10 times the mass and 20 the fuel capacity. Note that the B-25
was trying to land, and so was low on fuel, whereas the 767 was nearly
full. Also note the impact wasn't what took down the buildings...it was
the heat of nearly an hour of intense aviation fuel fire (probably
softening the steel structure).
