New 9/11 documentary captures ground zero before towers collapsed

For most of us footage of the ghastly 9/11 attacks in New York is something we will never forget in our lives. But it seems there were other aspects of the attacks that we never got to see.

A 2011 documentary, released on YouTube on May 4, carries the only known footage of the first plane flying into the World Trade Centre.

The CBS documentary, ‘9/11: Ten Years Later’, also has some shocking and yet unseen footage from Ground Zero.

In one of the shots, the camera person follows Fire personnel inside one of the buildings in the complex. As they walk amidst the debris, the two towers are still standing, though on fire.
