knockout gas? why not happy gas? let us all get high on our flights, and i bet people would not hate flying as much. locking the cockpit aint a bad idea, but where would they pee? airlines ARE cheap, and another bathroom is probably a bit much to ask.

as for explosive decompression, its only explosive when you have gaping holes ripped into the plane. and low calibur sidearms, especially with frangible or hollowpoint rounds, would probably be stopped by the fusealage. tazers, shock batons, KO gas (even in a canister delivered by the skycop) or gel rounds would be perfectly effective. I would stand by bullets tho, they have a long track record for getting the job done, and sometimes the risks are sufficient to mandate their use.

hell, i dont care if he only has an expandable ASP baton, just having the guy on the plane would be an effective measure. its called a deturant force, it does not matter if he is passenger 47 or not, as long as he is one more obsticle that potential hijackers would have to deal with.
