GeeSussFreeKsays...Flying, in a thermodynamic sense, is the least energy intensive way to move on this planet. On land, you have to deal with both wind friction and tire friction, not to mention turbines are one of the most efficient way to do ICE engines. To think, if the planet a bit larger, and the air a bit denser (as a result), the skies would be the new seas and whales would fly high as eagles.
