If you’re referring to WTC 7, it didn’t spontaneously collapse, it collapsed because of a fire. There was 91 000 liters of diesel fuel stored in that building for generators. Anyway, a few years ago a similar university building collapsed in Netherlands I believe. Even if it didn’t, just because something happens the first time, doesn’t mean the official report is wrong. A lot of things happen the first time, like a nuclear plant has exploded only once in history.

The NIST report states that fuel had nothing to do with the collapse.
So we can all have it as a reference instead of vaguely referring to it, here’s a summary: http://www.nist.gov/public_affairs/factsheet/wtc_qa_082108.html
