... #ad▼New video has surfaced of the burning World Trade Center towers on 9/11. It was was shot from a police helicopter and was released after a FOIA request by the National Institute of Standards and Technology, which investigated the incident.
After burning for 56 minutes, the World Trade Center South Tower (2) collapsed. Thirty minutes later the World Trade Center North Tower (1) collapsed. The attacks on the World Trade Center resulted in 2,752 deaths
Was the video lost? Releasing it after 10 years is little strange to me.
