I could not understand your line of argument, th3 ied kid!

well i assume myself to be hijjacker for a moment and think am flying by your crazyengineer airlines! first if i had a gas mask my job of eluding sedation gets done!

You should read previous replies. As mentioned earlier, even if you carry the gas mask with you (if the security allows you to do that), you will be protected for a limited time.

next i dont need to hold that gun pointing at your plane drivers(sorry guys i canyt sppell piolet correctly!) coz i would rather threaten the hundreds travelling by your airlines!that should be heartfull enough for some governments to suggest negotiations with me!
next thing if my negotiations fail , the aircraft would be landing in some location which the govt feels is secure enough and then i gain company!
either i die or there is mass murder!

Without a gun (or a weapon) how would you ( the hijacker) threaten the passengers?

Remember that the initial plan says that the cockpit is sealed from the rest of the aircraft. So at any point of time, the aircraft will be controlled by the pilots. There is no question of the aircraft landing anywhere else but its destination.

making passengers sleep in AIR could help our AIRLINES go bankrupt anytime coz of those PETA/ANIMAL RIGHTS ACTIVISTS banging at our director's doors

This point is interesting. I, personally, would prefer sleeping in the aircraft instead of getting killed in the air

Air Marshells is a good idea though
