Good post "Guppy" - I doubt if in the calm confines of a non-hazardous room, that an oven-roasting bag would give you 2 minutes breathing time and it should be remembered that in an 'incident' the breathing rate would be much faster. If anyone feels so strongly about smoke/fire survival on board an aircraft, why economise on the choice of perceived 'life-saving' equipment? How much is your life really worth, if you have to resort to carrying oven-roasting bags?
