I also had friends at the WTC. They got into the lobby but didn't go up. If they had, they would have been among the victims. Personally, I would have preferred him being blown up, just like his victims.
The group I felt sorry for were the passengers in the plane that went down in Pennsylvania. Had one person with any aviation experience been on board, they probably all would have survived. I know I could have kept that plane in the air and got it on the ground in one piece, without any prior flight training. The problem that plane had was, when that wrestler pulled the hi-jackers out of the cockpit, the autopilot was deactivated and the plane was put into a dive. Had one person taken control of that plane, all of the passengers would have lived.
