911 the new unpublished video

Dear comrades,
This is the first time I put this video on the internet. I got it from my late brother who lived in Martha's Vineyard and he got it from some Czech tourist who traveled for the first time to New York. By chance, they filmed the 9/11/2001 attacks on both buildings.

This is the shorter version of the original video. He taped the whole event in real-time including the collapse of the buildings. Video actually proves that the buildings collapsed thanks to the compromised structure by the impact of fire and not by any controlled explosion.

As far as I know, this video has not been on the internet till now because it is sitting somewhere in the safe as I was told by my brother before he died.
I used to show this video to my students because when you see the event in the real-time you have incredibly different reactions to it.
