看样子应该是从里面往外烧的,而且着火的地方比较低。应该不是由烟花引起的。

  • Like Beijing needs more smoke rolling through their air...

  • In 1945 a military plane crashed into the empire state building...You see a steel building doesn't fall from a plane crash and fire.

  • WOW this fire went out of control in less than a minute.BAM.

  • @drew936 also it melts at 2500 as in molten form now at 1200-2200 you can soften the metal to form it in the shape you need

  • Because they weer made to withstand fires like these, this isn't the USA.

  • yeah, a crash from a 737, not a 767 or 757

  • BTW, an object's kinetic energy (how big a bang it creates when it crashes) is directly proportional to the mass of the object, and proportional to the square of its speed, so trying to hit a building at high velocity as opposed to slowly trying to get out of the city is kinda important.

  • I did do some research. The building was designed to withstand an accident - the impact from a smaller airplane that had dumped most of its fuel and flying slow, not this big, with all its fuel left, flying fast - trying to hit the building. The impact explosion destroyed floors that were lateral stability for the columns, making them typically three times as long and maybe 1/16 as strong. Steel columns don't have to melt to loose capacity if the buckling length increases.

  • If you really did some research, you would find that the design of the towers was in fact made to withstand an airplane crash. Steel melts at 2500 degrees Fahrenheit and the jet fuel burns at around 1700 degrees Fahrenheit. There had to be other external or internal forces that contributed to the towers collapse.

  • Buildings are supposed to NOT collapse in a fire. The structure can take a beating. WTC couldn't, because the event was out of everyone's wildest guesses at the time of design. There were no aeroplanes that big back then as the design worst case. The impact shredded parts of the structure that was meant to help WTC withstand the fire. In Beijing, the important issue is why the fire got out of control. That is NOT supposed to happen; there should be fire compartments that prevent that.
