1. Medical problems some passengers may have with the gas? While it might be a reasonable tradeoff to lose a passenger or two if the whole plane (and whatever it may hit) can be saved, making that determination that early (at the first sign of an hijack attempt) would likely be impossible.

Worse than that if you think about it... Given that there are about 4000 major flights a day, in a given year, thats about 1.2 million flights a year. So, if your gassing-system is 99.999% reliable, in that there is a .001% chance of it being triggered accidently in any flight, you'll gas about 10 flights a year (say) a thousand people, unnecessarily. In 10 years, the time since the last hijacking, you'd gas about 10,000 people. Compare the disruption and possible deaths caused by those gassings with the slim benefit they might have against determined and thoughtful hijackers, who haven't hijacked a domestic airliner in 10 years. Now, this is nanog, we know how hard it is to obtain 5x9's of reliability. After running the numbers, IMHO, its a really really bad idea. Scott [*] Number of flights per day are taken from CNN.
