Speaking of jet fuel, there's a compelling theory that commercial airline planes in particular, do not primarily run on fuel. The theory is that they use fuel to take off and land but while they are in the air, they run on compressed air. Look at how many gallons they tell you that any particular airliner holds and then look at that amount of gallons in a container next to the plane. There's no f****** way that the amount of fuel they say fits in the wings, does.
