This is very disturbing. I also find it disturbing that the people in tower 2 were told by the port authority to go back up to their offices, that their building was secure. There has been very little press coverage of that, and I think it should be investigated. Virtually every story I've read about survivors has mentioned that fact, yet there hasn't been one big story to pull all those recollections of that information together. You're right; there should be an investigation of this.
This is not a movie stage. Bruce Willis wasn't going to run up the stairs and save the day! Next there will complaints that everyone didn't have one of those idiotic parashooots to sit next to their desks.
