from AW&ST, US airplanes, civil and military, bought (= burnt) 25 billion (US) gallons of fuel in 2008. using round numbers that's 100 billion liters. assume an AFR of 12, so that fuel combined with 1200 billion liters of air. so 240 billion liters of O2 were consumed ... gone.
forget the CO2 produced, each gallon of gas consumes 10 liters of O2 (in nice round numbers, easy for a politician to remember).
we're doomed ... well, of course we are ... at best 1 person has made it out (and come back to tell us) compared with well over 1 billion fails (if they made it out, but didn't come back to tell us, then they don't count !) but what about psychics (communicating with spirits, = people who made it out) ?
