Years ago I had a subscription to Air Classics. There was an article in one about a gent (I think he lived in the midwest) with a small ranch.
He had a small plane, high wing cabin job, Aeronca IIRC. No land for a long straight runway, the man was restricted to a patch of ground that was perhaps 100 ft. in both directions.
He rigged a cable ('tether' style) to the port side of the fuse, at the center of balance...then warmed the engine up, and taxiied round 'til airborne.
When he reached '60 knots' (or thereabouts) he cut the plane loose, flying off with no strain!
He somehow had space to land, then taxi back to his takeoff point.
Anybody remember this story? Not so 'impossible', as the Alaskan Bush pilots land on the sides of mountains, then turn the airplane and take back off with a downhill taxi...
