Dream Buster.
No oneupmanship intended. I mentioned my incident only because on a good day with a following wind and eight hours sleep I'd say I'm average and certainly no ace. I also believe that the current system(s) of crew mask deployment coupled with aural and visual warnings are enough. In the Helios incident they misunderstood the warning which I would suggest raises issues about (maybe) training and the warning system on that aircraft. I don't think there is enough evidence of similar incidents to warrant the redesign and retro-fitting of thousands of aircraft.
Affordable safety? Perhaps but I also think there is some merit in the suggestion that the current system is also the best ergonomically. In the interests of preventing further thread drift or being moderated I'm happy to agree to disagree.
