The De Bothezat Helicopter
Prof. George de Bothezat, inventor of the helicopter with which highly interesting trials have been conducted at McCook Field, Dayton, Ohio, for the past six months, recently was paid a fine tribute on the part of Col. T. H. Bane, former commandant of McCook Field, who piloted the machine on most of its trial flights.
