If you are on a transpacific or transatlantic flight,
and there is a loss of cabin pressure, how long
do the oxygen generators have to last? (the ones
attached to the masks that drop from the ceiling)

If they only have to last 30 minutes, the pilot would
have to descend to an altitude where there is enough
oxygen to breathe. But this would increase the fuel
burn of the engines. Would there be enough fuel to
get back to land?
