Conspiracy theorists have long claimed that explosives downed World Trade Center 7, north of the Twin Towers. The long-awaited report from the National Institute of Standards and Technology (NIST) conclusively rebuts those claims.

The report also raises concerns that other large buildings might be more vulnerable to fire-induced structural failure than previously thought.
