At the risk of sounding a more somber note, didn't the passengers of Flight 93 use a drink cart to help batter down the cockpit door?

As far as this keychain "weapon" is concerned. it seems to me a more effective weapon could be improvised on board--especially if the passengers and crew were cooperating.

Wow---what a novel idea.... maybe it takes a true life or death struggle to get that to happen <img src="/images/graemlins/ooo.gif" alt="" />
