Launching of heavily loaded bombing planes by means of a captive arm or wing has been proposed by an English inventor, P. B. Shead. The device would whirl the plane around and around until it attained sufficient speed to be released into the air. The wing would be driven by powerful gasoline engines and propellers. When not in use the outer end of the wing would touch the ground. A plane ready to be launched would be fastened to this outer end and its engines, with those on the wing, started to swing the wing around. At the proper speed, the plane would be freed, with centrifugal force helping to give it a good start. A model of the launching “merry-go-round” built by the inventor indicates that the wing is designed to give the correct angle for the plane’s speed and radius of turn, thus avoiding complications resulting from an aircraft being flung off at a tangent, instead of heading into the wind. The cradle in which the plane rests on the wing is close to the ground, when the arm is at rest, making it possible to load planes easily.
