Hi,
1908 = This father-and-son team built a full-size 1p helicopter with 60hp
Hall-Scott V-8, and two hinged 16' rotors mounted on a triangular, steel-
tube platform—a primitive VTOL concept. "Planes" indicated in the linked
drawing are curiously shaped, unexplained, and do not show up in a photo
that appeared in 1909 Jane's.Not only that, but that craft looked entirely
different from this side-view sketch in 1908 Jane's, which shows a quad-
gear cart with sulky wheels under a frame with two circular helical rotor-
forms fore and aft, and no rudder. The only thing in common with the two
is an identical report that during an unmanned full-power trial in a shed,
in July 1909, it broke its tethers and ambitiously smashed itself into the
ceiling. Technically it did fly, but in which of its forms is unknown.
