9/11 reference to people who think it was an inside job.

Yeah but what part? Does a plane fly into some direction because it bursts?

It says "Jet fuel doesn't melt steel beams." Which is true depending on the beam, but the steel beams in the WTC didn't need to melt to fail. They just needed to be heated up to a point their yeild strength is lower than the weight of the building above it and physics takes over from there.

The steel beams that failed in the World Trade Center were primarily the floor trusses, which supported the floors between the columns. The intense heat from the burning jet fuel weakened these beams, causing them to lose their structural integrity and ultimately leading to the collapse of the towers.

Thanks ChatGPT lol

So the plane crashed into the building and there was a floor carried by steel beams and those bent and caused the whole building to collapse.

Basically yeah. Once the floor buckled everything it supported did too, meaning a mind boggling amount of mass started moving and there's no way to stop that much mass from falling at that point.
