Ah, that's too bad. I wonder if he'd pass the ornithopter on to someone willing to continue it's showing at airventure.Steve and Jim Hays have retired from doing the antique engine stuff and quit coming to OSH. Age catching up is the last I heard. While many knew them from the Stone Age Ornithopter, they were also the folks who built and maintained a number of accurate recreations of the Wright 1903 engine and some later Wright engines as well. They were noted for starting one on a daily basis in the Antique area at OSH during the convention.
