Yes and the B-25 that hit the Empire state building caused no damge to any of the steel beams. You might want to try to post the whole facts next
time.
Ok - been over this before....
Difference in building construction
Empire State Building - infill construction, exterior 8" thick quarried
limestone , structural members are heavy steel beams cemtered 35'
floor heavy steel beams with metal decking cover by 7-8" cement
WTC - exterior was 30 ft panels of light gauge steel bolted togather,
lightweight steel trusses connected to central core columns, floors
are metal decking with 3" lightweight cement (4" lower down)
Impact as described above was only about 1/100 that at WTC, smaller
aircraft moving at 1/3 speed of WTC aircraft
Steel columns in Empire State covered by 4" of concrete or terra cotta
masonary as per 1938 fire codes.
Steel columns/trusses coated with 1/2" spray on fireproofing or 5/8"
sheetrock
Fuel load - B 25 max is 2000 gals, only fraction as short ferry hop
WTC - 767 over 9,000 gal Jet A
Differnce is forces is like being shot with BB gun vs 44 mag - one is
going to do lot more damage
