>>1656022don't talk about stuff you don't know anything about. facts are that jet fuel isnt hot even when burning, proven on mythbusters when jamie died crashing a plane into the empire state building.

C) what actually happened was they landed the plane inbetween floors, everyone got out and ran downstairs while they lit a fuse that blew up the explosive pillars.
