"The WTC primarily used concrete in each floor, and it was just a few inches thick and would also pulverise when hit by the floor above." NO! THAT is the most obviously wrong thing you've stated. Drop a piece of concrete onto another. Drop a piece that weighs 10 times that which is being dropped on. Drop it from 15 feet...25 feet...35 feet...100 feet...500 feet. Neither piece will pulverize the way the concrete from the WTC did. ESPECIALLY the concrete in the WTC that was pulverized during the first couple of seconds of falling. You do know what the acceleration due to gravity is don't you? Physical evidence in the form of photographs and videotapes shows complete pulverization of the cement of the upper floors when it was falling at a velocity of only 30 feet/second. 30 feet x 60 seconds is 1800 feet/minute. 1800 feet x 60 minutes is 108000 feet/hour. 5280 feet/mile...so... 108000 feet/hour divided by 5280 is 20 miles per hour YOU claim that concrete hitting concrete, in the pancaking scenario, at 20 miles/hour is enough to pulverize the concrete. Do you realize how utterly ridiculous you are being?
