Patent No. 1,181,784
Issued: May 2, 1916
Inventor: J. McCurry, Philadelphia Pennsylvania
An invention designed to allow a platform (13) to hover over one spot for military surveillance or photography. Two airplanes (5) and (6) are roped together at the wings or fuselage, in opposite directions (i.e. both right wings are tied together), and attached to the platform by cables (10). The cables are long enough "to avoid embarrassment from the noise of the aeroplanes". The airplanes then fly in a tight circle, causing the platform to hover over the center of the circle.
