Not according to the 911 telephone transcripts. Someone called and said they were one of 40 people who had made it to the roof and asked 911 for instructions on how to save their lives. The people in Tower One said that the excape doors into the stairwell leading up to the roof or down to the groudn were blocked with debris that had fallen during impact. But there WERE 40 people on the roof as of 20 minutes BEFORE the collapse.
I sure would like to hear those tapes. Do you have a link? They had a Port Authority spokesman on Fox a few days ago defending their decision to lock the roof doors to prevent suicides.
I hope what you heard is true but after that press conference I would like to hear the tapes myself.
