Questionable Quidity: on Rowing Flying Boats, 1889

JF Ptak Science Books Quick Post

This remarkable flying machine was patented by N.H. Borgfeldt (of Brooklyn, NYC) on 1 October 1889. It really seems to be not that much more than the rowing-section part of a Roman galleon, except that it is in the air; there are five "rowers" int his aircraft, plus someone to operate the rudder. And a flag.
