This is the first hour of the 9/11 attacks, as seen from my window at the time. Significant events happen in the first minute of the video (second plane hitting the south tower), at 39:00 when the south tower collapses and at about 52:00 when the north tower collapses.
Listening to my voice on that day, and the background newscasts, are the most chilling part of this video, IMO.
Sorry for the watermark. Too many have tried to steal this video.
