Which one of these things is not like the other?

The freefall collapse of World Trade Center building 7 (WTC7) compared with other known controlled demolitions.

Contrary to the conclusions of the National Institute of Standards and Technology (NIST), the University of Alaska at Fairbanks (UAF) research team found that the collapse of WTC7 on 9/11 was caused not by fires but by the near-simultaneous failure of every column in the building.
