Okay, I'm gonna edit this later on, I'm gonna try find the source of this, but from I read, the NIST believes the World Trade Centers couldn't have collapsed under the cicumstances described in the 9/11 comission report.
Well, after all, fires don't melt steel within less than one hour and fourty minutes.
Okay, here goes...I'm sorry for this.

2. Intense fires lasted only minutes
The NIST report states that: “The initial jet fuel fires themselves lasted at most a few minutes and office material fires would burn out within about 20 minutes in a given location." (NIST, 2005; p. 179.)
This is further corroborated by the fact that intense dark choking smoke was being emitted from the towers before they collapsed indicating the fires were oxygen starved and burning at low temperatures.
In addition NIST stated that of the more than 170 areas examined on 16 perimeter column panels, only three columns had evidence that the steel reached temperatures above 250?C… Only two core column specimens had sufficient paint remaining to make such an analysis, and their temperatures did not reach 250 ?C. … Using metallographic analysis, NIST determined that there was no evidence that any of the samples had reached temperatures above 600 ?C. (NIST, 2005, pp. 176-177)
At any given location, the duration of [air, not steel] temperatures near 1,000oC was about 15 min to 20 min. The rest of the time, the calculated temperatures were near 500oC or below.” (NIST, 2005, p. 127, emphasis added.)
