Reading that gives me the heebie jeebies. But you remind me of watching my friend's father do just that very thing, except not as high as FAA-approved trees. It was the funniest damn thing you ever saw, even though you just 'knew' he was gonna' ball it up. Unplowed cow field cross fenced every coupla' hundred feet with a ditch crossing right down the middle at the start of his roll. He's in his lil 'ol Airknocker with an engine block and associated parts as cargo. He lights it up and about mid way he pitches up--as my stomach sinks like a stone--clears the 1st fence, mushes in, bounces into ground effect, pitches up to clear the 2nd fence never really flying, just mushing along....and so on over 2 more fences until he drops out of sight off the 50' bluff at the ocean's edge. So help me God, there's 'ol Bob skimming the watery deck until he gets enough juice to carry him up and away. He comes back over us and yells out he's good to go and heads off for his destination.
As reckless as he seemed to be the man was an honest to God seat of your pants engineer. You can bet he calculated his minimum required performance. He had over 50 patents, he hand built 11 planes, his engines are spread throughout the 5 western states, among many other things, he designed and built race engines, no use for blueprints. Barney Oldfield won many of his races with Bob's engines.
He passed away two weeks ago an old man. He'd have lived another 400 years in it weren't for the cancer.
He also taught me a trick for getting a tail wheel out of a too short field. Years later Sparky Imeson mentioned the same technique. Start your roll heading about 135* opposite to your intended departure path. Get up some speed and start to circle 'round through 180* all the while gaining speed and once aligned with your departure raise the tail and up an away you go. No, I haven't tried it.
Okay, I'm finished with my thread creep.
