I heard that too. There was a heavy door barring entry to the roof, from what I heard.

CNN printed the transcript from a cellphone call saying that he/she was one of 40 people that had reached the roof (I don't know which tower). The caller asked 911 "tell us how to save our lives". Also, the reason the Cantor Fitzgerald people were not able to reach the roof is that the collision caused debris to block the fire doors into the stairwell to the roof ... that doesn't preclude other higher floors being able to reach the roof.

Thanks. The facts are very confused. Supposedly the choppers were ready to pick up people but did not. At any rate, this was a disaster caused by evil criminal minds.
