The trailblazers hellraisers want to learn to fly, but first must learn to try and not begrudge the birds their wings or beaks or things. It's each to his own and birds have flown for centuries while man looked on quite jealously, until Wilbur and Orville an unlikely looking pair, built a weird looking craft that flew into the air and there the story lies. Man no longer separated from the skies but flying catatonic,supersonic,chronically intoxicated by machines that he's created.
It will all come to pass that when we run out of kerosene and natural gas, we'll recognise that flying free is but a dream and then we'll see that wings are meant for birds and no amount of whirlygigs,tornadoes,migs can change the fact that we were made to walk.
