A video taken by a NYPD helicopter as it circles the burning World Trade Center towers during the immediate aftermath of the 9/11 terrorist attacks is quite possibly one of the most chilling events ever caught on tape. The video was recently released and can be viewed here.

The clip is approximately 20 minutes in length and the copter hovers incredibly close to the Twin Towers after both had been hit by commercial aircraft. The copter gets dangerously close to the burning buildings… almost too close. It is incredibly difficult to watch with such a bird’s eye view, even though it is essentially a historical document.

The video also captures the collapse of the Towers from a safe distance. Someone is heard saying, “We got out of there at the right time.”

Did you watch the video?
