And you dont think it's odd that no other building has ever collapsed due to fire. Your doing better than NIST, because they don't have a clue why 7 collapsed. They are even forced to investigate possible blast scenarios now.
Have you read NIST's interim report on WTC7?
Perhaps you are confused. FEMA stated in THEIR report that they had no idea why WTC7 collapsed. NIST have released a relatively detailed interim report on WTC7 which includes their hypothesis on what caused collapse.
WTC7 did not collapse due to fire. It collapsed due to extensive structural damage AND fire.
Plenty of buildings, all through history, have collapsed due to fire. Indeed, buildings collapse for many reasons. The myriad of causes, myriad of different building types, combined with modern safety standards (that make collapses from any cause relatively rare in this day and age), make repetitions of exact scenarios highly unlikely.
For example, in 1995 a shopping mall in Seoul collapsed, killing over 100 people and injuring nearly 1000. I would be quite surprised if such a scenario has exactly repeated itself anywhere else, as I imagine shopping mall collapses are rather rare.
Does that make this collapse rather suspicious? No, it doesn't.
Or, looking at 9/11...
9/11 was the first time anyone had EVER purposefully flown a commercial airliner into a building. And yet on this one day it happened three times.
