Wireless telegraphy, typically the transmission of messages using radio waves, enabled wireless transmission of messages from aircraft.

Electricity for the radio came from the moving propeller:

A small air screw, placed at the front of the airplane and rotated by the wind when the craft is flying, supplies the mechanical force which drives the dynamo. Direct current (D.C.) is thus produced. But direct current cannot be transformed to the high voltages (pressure, or electromotive force) necessary to transmit the radio signals through space, so alternating current (A.C. is produced in a special dynamo, or alternator.

The first "in-flight" (=airplane?) wireless link occurred between J. A. D. McCurdy and Percy Morriss in 1910.[1]

Radio, as a means of control, has slightly entered into our data in connexion with the work of Lucien Fouque‎ as exhibited in his Patent FR-1909-399976.
