Wired 13.06: START: "For more than four years - steadily, seriously, and with the unsentimental rigor for which we love them - civil engineers have been studying the destruction of the World Trade Center towers, sifting the tragedy for its lessons. And it turns out that one of the lessons is: Disobey authority. In a connected world, ordinary people often have access to better information than officials do.

Proof can be found in the 298-page draft report issued in April by the National Institute on Standards and Technology called Occupant Behavior, Egress, and Emergency Communications. (In layman's terms, that's who got out of the buildings, how they got out, and why.) "

...

"Also, occupants of the towers had been trained to use the stairs, not the elevators, in case of evacuation.

Fortunately, this advice was mostly ignored. According to the engineers, use of elevators in the early phase of the evacuation, along with the decision to not stay put, saved roughly 2,500 lives. This disobedience had nothing to do with panic. The report documents how evacuees stopped to help the injured and assist the mobility-impaired, even to give emotional comfort. Not panic but what disaster experts call reasoned flight ruled the day."
