gcal...unfortunately there is the 0.111111 percent that resulted in 3000+ deaths in 2001. I really don't understand why you and others are burying your heads in the sand over this issue..there is a flaw in the system here and I don't understand why you don't acknowledge the fact..I'm not criticizing air crew in any way..just pointing out what I consider to be a potential problem for air safety. As for cabin crew being able to 'minimize the chance of being overpowered' - I'm afraid I don't feel reassured at all.
