World Trade Center 7 was the third tower to collapse on 9/11/01. It was a 47 story steel skyscraper (not hit by a plane) that fell straight down into its own footprint at free fall speed, at approximately 5:20 P.M. local time. The official cause of collapse from the National Institute of Standards and Technology is "normal office fires".
