Hundreds of lbs of jet fuel exploding can help as well.
Yes...but who barbecues their meats at over 1500 degrees? It could be done but not for very long.
And yes...I did detect your sarcasm.
Rosie said it was so. thus it is so. Who are you, a mere conservative to question God?
This is the first time I’ve heard they were designed to fail in this way.
The truth is, even thought their designers just weren’t evil enough to comprehend such an attack (and were thinking of hurricanes), the way they collapsed was the safest to the city so they worked.
I am sure some died in the cloud of debris but not as many as would have had the tower fallen intact.
Never thought about that before.
IIRC the plans for the WTC were finalized in the late 1960's when the biggest,heaviest *commercial* planes in use were the 707/DC8.It's my understanding that the WTC *was*,thanks to the incident with an Air Force plane and the Empire State Building in the 1940's,designed to withstand the impact of a 707/DC8.If that's true then one would think that the impact expected wouldn't have been at 400-500 MPH as was was the case on 9/11.Also,a 767 is a whole lot bigger and heavier than was the 707/DC8.
Perhaps not...but it surely can be weakened by exposure to intense heat.
I think he must have rubbed his head with Icy Dumb.
A 737 going 500mph I think would do more than just take it offline.
So that explains his poor free throw shooting percentage!!!
Hakeem Olajuwon took him to school, in a 4-0 sweep, in the NBA finals back in ‘95 I believe...
Awwwwwwwww...pity poo poo poodoo...;-)
Agreed, the mass will penetrate. Now, how does it make a 110 story building come down at free-fall speed pancaking the floors one by one?
When one floor's metal supports weaken due to the extreme heat.
Why did the buildings collapse?
To put it simply; The impact of the plane shook loose the sprayed on insulation that is supposed to protect the structural steel members exposing them to the intense heat of the jet fuel fires generated from the fully fueled Boeing 757s.
The structural steel weakened by the fire then collapsed under the weight of the floors above the fire. The floors above slamming in to the floors below collapsed those floors in turn.
Popular Mechanics did an excellent job explaining in the article below.

Remember, the largest plane at the time was a 707.
