The LATEST Nist revision to the cause is quite "out there". Now they say that dislodged fireproofing from the impact area is why things gave way 
Seriously, read the report. Thats exactly what they are telling us now. Remember those beams and steel met 2000 degree temps for two hours unfireproofed just to meet code(they performed perfectly). No fire burned two hours, nothing got anywhere near 2000 degrees.Hydrocarbon fires cant and dont burn that hot.
So how does Nist test for dislodged fireproofing to back they're story?
They shoot a 12 gauge shotgun into a plywood box 15 times coated with fireproofing. Thats exactly how. Google it and get an education  |

Pretty darn close...the beams were significantly weakened.
