Designed and built by Oscar C. Rosen, this wireless transmitter made the first successful radio transmission from an airplane to ground in 1911. It was carried aboard a Curtiss aircraft piloted by J.A.D. McCurdy. The airplane could not carry the additional weight of Rosen, so the telegraph key was attached to the control wheel, and McCurdy sent the message.
