Re: The change . . .
I think all it would really require is one airline adopting a smoke hood contraption for its clients, then advertising it to active and potential fliers and a safety feature no other airline will supply. Other companies, though, would soon follow suit, with a nifty little "new and improved" hood of their own, which would build into others with additional safety features the industry currently finds financially cumbersome.
All it takes is one to start trouble for everyone else...
