A man has posted never-before-seen footage of the collapse of New York’s World Trade Center towers.

Treasure found by accident in a closet

While going through his old belongings, Kei Sugimoto stumbles upon several videotapes. One caught his eye: it was dated September 11, 2001. He immediately decided to digitize them. What he discovered was beyond his wildest dreams. The footage, shot with a Sony VX2000 camera, offers a rare perspective of the collapse of the World Trade Center towers, captured from the roof of an East Village building.
