Congrats to the crew involved regarding proper use of the crash axe.. . . .Only one further comment. If there is a signifigant threat on board the aircraft (ie, someone with explosives in his shoes, or someone who has attempted to break into the flight deck) - that person might continue to be a threat if they "come to" or get lose from their restraints. Personally, I believe the safest course of action would be to drop down to an acceptable altitude, depressurize the plane, open the door and eject the offending individual from the aircraft.
