Jet fuel can't melt steel beams

A phrase referring to 9/11. This phrase is normally used by conspiracists that 9/11 was inside job carried out by the U.S. under President George Bush. The argument is that the steel beams that collapsed within the tower causing it to fall, could not have been melted by the heat from the collision of the plane. Meaning that the building could have been intentionally brought down via explosives, specifically using thermite, that can melt steel and leave no evidence behind.

Person A: 9/11 was such a mournful day in history. Screw Terrorists!!
Person B: Yeah....the terrorists are the government. Jet fuel can't melt steel beams.

Jet fuel doesn't melt steel beams 

That "jet fuel doesn't melt steel beams" is a conspiracy theory based on 9/11. The name gives it away but it basically means the planes did not singlehandledly bring the towers down but someone had made them vulnerable on beforehand. There's also a conspiracy theory based on the twin towers not being built with steel beams in order to save money. "Jet fuel doesn't melt steel beams" is often associated with George Bush since he was the USA president at the time.

Brandon: 9/11 was such a tragic
Robert: It wasn't an incident, jet fuel doesn't melt steel beams!

Jet fuel can't melt steel beams

A common statement by idiots who think 9/11 was an inside job. They say that the Twin Towers shouldn't have collapsed because jet fuel can't melt the steel beams that the towers were made out of. Although it's true that jet fuel can't melt steel beams, the Towers Collapsed because the steel beams were weakened from the fire, not melted. The conspiracy theorists are too retarded to realize this fact.

Idiot: 9/11 was an inside job done by George Bush!
Smart person: No it wasn't you fucking dipshit
Idiot: But... but jet fuel can't melt steel beams!
Smart person: The jet didn't melt the steel, it weakened it. Do more research, moron.
