My God, we're so paranoid. We sound like...........Americans?? Stink bomb.....who cares??? If they can get Hydrogen sulphide on now.....well jeez, that makes it pretty obvious they can get mustard gas on board...or maybe a bit of Bird flu?? I'm never flying again.......and I'm buying a big gun to protect myself.
Relax
PS. Twasn't me!
