Here's an actual archfag who has spoken to an experienced civil engineer about this, so listen the fuck up.

Jetliners are heavy chunks of metal. They flew into the towers at about 600 kmh, fully laden with fuel. Thats a lot of mass going fucking fast, not to even mention the fuel. The wings cut through structural members. Once a certain number of floors start collapsing, its really all over as the floors below arn't strong enough to stop dead all of that weight landing on them. This is known as the pancake effect and its really common sense.

The second part: picture a thin wooden dowel. If you compress it vertically its very stiff. However as soon as it deflects even a little sideways, it becomes very easy to subsequently snap. This is the same as the wtc columns. The impact of the planes caused the beams to bend or "wobble" ever so slightly off center axis, and at that point the compressive strength of the concrete is nullified and the whole thing "snaps."

TLDR fucking giant planes did it faggots, deal with it. This is from someone who agrees the government would not hesitate to kill thousands of people in a false flag attack but come on - 9/11 is pretty clear cut.
