Video shows what happens when a plane hits a firetruck — and people are asking how the same physics knocked down the Twin Towers

A Plane Hit a Firetruck. The Firetruck Won.

A video went viral showing what happens when a plane collides with a firetruck. The result? The firetruck barely moves. The plane disintegrates. Now people are asking a very uncomfortable question: if a plane can't move a firetruck, how did planes bring down two of the strongest buildings ever constructed?

The Physics

The Twin Towers were engineered to withstand the impact of a Boeing 707 — the largest commercial aircraft at the time of their design. The buildings absorbed the impacts on 9/11 and remained standing. What brought them down, according to the official narrative, was fire weakening the steel. But the fires burned for less than two hours, and no steel-framed high-rise has ever collapsed from fire before or since.

The Viral Moment

This video hit nearly 7,000 upvotes on r/conspiracy because it does something no amount of text can do: it shows you the physics. A plane hitting a solid object doesn't make the solid object vaporize. It makes the plane vaporize.

The Question Nobody Answers

If fire brought down the towers, why did they fall at near-freefall speed? Why did Building 7 — which was never hit by a plane — also collapse at freefall? And why did the 9/11 Commission's own co-chairs write a book saying the investigation was "set up to fail"?
