This was my grandfather, Lehman Weil (1861-1940). My father William remembered him trying to get this off the ground in Staten Island c. 1910. It was far too heavy and I suspect the design left something to be desired, but at least he tried. Incidentally I am licensed as both a private airplane and a commercial glider pilot.
