1. Jetfuel burn at higher temperatures
2. A plane ******* flew into the building which damaged the steel "carrying" the buildings
3. OP is massive faggot and sucks dicks on a regular basis

1. Jet fuel burns at 260-315C .
2. Steel melts at 1,400-1,540C.

Think, if steel melts at lower temperatures then Jet engines hit, why the engines don't melt?

lol americlaps don't think. CLAP-CLAP-CLAP

Weakened metal due to the impact, weakened further due to the heat, wasn't necessarily melted, but softer, the floors above weight causes the supports to give, all that weight is then suddenly dropped onto the floor beneath it and so on, it's sort of like having a human pyramid, and then one level of people just give, and the sudden weight put on the level below causes it to collapse as well.

Where in my comment did I say that the steel did melt?
I just said that jetfuel burns at higher temperatures.
You must feel real proud of yourself for telling me something I know

the structure was built to withstand 50+ plane crashes before falling
ask the architect

Who told you that? There is no way an architect would design a building. Step back and think to himself "Well. That looks like it could withstand about 50 planes"

What do you mean? They don't do that anymore? My house is rated at .05 private airplanes, or .004 (+/-) .001 commercial airplane crashes. I thought that's how they rate the structural integrity of all buildings.

Actually for example in Germany and other European countires skyscrapers have to be have a steel construction which is surrounded by concrete. So when a fire breaks out the concrete isn't affected and the building won't collapse. I think they build stuff in Europe like that since the 60s, so even bevor WTC was built.

Concrete explodes under high temperature.
