What about the fact that explosions can be seen coming from the sides of the twin towers before the collapse cycle reached that particular point.
Um, maybe it’s because the frame of the building is tied together by girders. Put a pencil on your desk and then push the eraser. Notice that the pencil point moves before your hand reaches the original location of the pencil point. It’s called Physics for 3-Year Olds.
What about the fact that the heat from jet fuel cannot melt steele.
Steel generally begins to weaken and de-temper at 540 F. Typical construction steel loses half its strength at approximately 1,090 F and virtually all of its strength at 1,300 F. In a completely open area, aviation fuel burns at anywhere from 500 to 599 degrees. In an enclosed space that has enough oxygen, the burn temperature is close to 1,800 F. The plane that hit the North Tower cut through the utility shafts, allowing fuel to spill to floor below and also causing an updraft through the shaft and windows that drew fresh air into the burn area, thus increasing the burn temperature.
Not only that, but the crashes themselves broke or twisted the columns and girders on a number of floors. WTC 1 sustained structural damage on 8 levels while WTC 2 sustained structural damage on 6 levels. The remaining structure was simply not strong enough to support the weight of the floors above.
By the way, my degrees are in chemistry and chemical engineering and I worked at an aviation firm for 4 years and have extensive experience with Jet-A, JP-5, and JP-8 fuels.
Before that, I was the lead chemical engineer for a large plating firm that specialized in aircraft components. After plating, most steels need to be heated for a period of time at 380 F to prevent hydrogen embrittlement. If the records from the oven showed that the temperature was somewhat higher, the parts had to be scrapped because the heat had weakened them.
In other words, I know what I’m talking about and you Truthers don’t.
And if you’re going to attack Bush politically, please explain why Sandy Berger found it necessary to steal and destroy on multiple occasions highly-secret documents in his socks and pants from the National Archives that dealt with Clinton’s record on terrorism. Somebody’s hiding something and it ain’t the Bushes. It was also the Clinton administration that erected a wall between the FBI and CIA as well as walls within those organizations.
