Video: New footage of September 11 attacks emerges
A chilling new video of the 9/11 attacks on the World Trade Centre buildings has been posted on the internet, showing the tragedy from a previously unseen angle.
Captured from a New York Police Department (NYPD) helicopter, the 17-minute video shows the aircraft hovering just 300ft above the Twin Towers as thick black smoke spewing out from the roof of the building.
After the 1727ft North Tower imploded, the police pilot can be heard on camera commenting: "Holy ----, that’s it, biggest disaster in the world, right there".
The footage was used at the official inquiry into the collapse of the World Trade Centre buildings. It was obtained from New York City authorities under the Freedom of Information Act by the National Institute of Standards and Technology (NIST) but was not released publicly.
However, the video was passed onto whistleblowing website Cryptome who leaked it onto the internet.
The September 11 attacks in 2001 consitute the worst non-wartime loss of life in US history, with 2996 people killed.
