The wife of one of the WTC victims said she was talking to her husband who had made it to the roof and was waiting for a chopper rescue.
I have done extensive reading on the idea of having helicopters rescue anyone from the roofs of the WTC on 9/11. My conclusion, based on those readings and my experience in the fire service, is that it was not a good idea. The primary reason is that it was too risky to attempt because of smoke conditions. Kinda hard to fly when you can not see. Especially near the roofs of those buildings, with all of the antennas, noxious smoke and such.
