It has been 16 years since the devastating attacks of September 11. Coverage of the tragedy during which nearly 3,000 perished was the main priority that day for most Western news agencies (the scenes were witnessed by an estimated two billion people – a third of the human race). Together with amateur records, this has produced such an incredible amount of footage, some of it is rarely seen even today.

A&D has collected some of the least seen 9/11 pictures from across the internet. From street-shots of the towers going down to satellite images of New York City, these unforgettable photos reveal new angles of the horrific day that changed the world for ever.
