@PalePimp@eee >Twin towers and WTC7 has ever been brought down on free fall by aerial front collision Those weren't brought down by the planes alone - it was all the jet fuel that lit a fire that burned for over an hour that ended up weakening the steel enough to cause it to bend like floppy spaghetti and lead to progressive structural collapse.
The Mohammad's were only expecting to wipe out the people on the floors that the plane hit, but they hit the terrorist jackpot and got 3 buildings with 2 planes and also hit the pentagon too.
The twin towers are so far the only buildings that have had jet airliners full of fuel flown into them and even then they did manage to stay up for a while, too bad there was no reinforcement around the fire escapes and most of them ended up getting blocked by debris and there was no helicopters sent for roof rescue either.
There was previously a truck bomb attack in the basement of one of the towers, but the bomber didn't park the truck close enough to one of the foundations to cause a collapse (a few people in that tower ended up surviving because the heavily reinforced basement resisted the whole tower collapsing on it).
@eee Funny how no other building besides the Twin towers and WTC7 has ever been brought down on free fall by aerial front collision, unless it is a targeted attack on the foundation.

As you can see that building collapsed in seconds, not 56 minutes and not 1 hour 42 minute afterwards.
If I was a glow in the dark CIA agent and wanted to take down the towers, I would have made sure the truck bomb had done the job in the first place (https://en.wikipedia.org/wiki/1993_World_Trade_Center_bombing?useskin=monobook), or lit a massive fire, or just rigged explosives - I wouldn't undergo the additional risk and effort to hijack passenger airliners and fly them into the towers, just to demolish them with explosives in the end.
Maybe the CIA was behind the plane hijackings, but it could have only been the planes that ended up doing it looking at the sequence of events.
@PalePimp@eee Reinforced concrete plus steel gravity column transfer trusses and girders, located between floors 5 and 7, to transfer loads to the smaller foundation.
The reinforced concrete part resisted the fire just fine, unfortunately the trusses and girders didn't, which failed and as a result the building collapsed.
@PalePimp@eee It looks like the huge fire is turning the steel trusses and girders into spaghetti.
As you can see, it burned for a long time before it collapsed and underwent a progressive collapse, with the top section collapsing first, then nothing for several seconds and then finally the superstructure collapsed.
A controlled demodulation would have brought the whole thing down in seconds.
