You're a little behind on your red herrings, papasmurf. Plenty of "high rise" buildings (typically defined by NFPA and others as having a highest occupied story greater than 75 feet above the level of fire department access) have collapsed because of fire. Other members of the "truth movement" have realized this and now are claiming that no steel-framed, modern high rise buildings have ever collapsed from fire (a much smaller population, and one with far less building-years). This is, of course, a stupid game to play. The WTC towers were not felled by fire alone, and WTC 7 was hit by portions of a larger building.
