In April 1934, many American newspapers printed a photograph of a man flying through the air by means of a device powered only by the breath from his lungs. Accompanying articles excitedly described this miraculous new invention. The man, identified as German pilot Erich Kocher, blew into a box on his chest. This activated rotors that created a powerful suction effect, lifting him aloft. Skis on his feet served as landing gear, and a tail fin allowed him to steer. What the American papers didn't realize was that the lung-power motor was a joke. The photo had first appeared in the April Fool's Day edition of the Berliner Illustrirte Zeitung. It made its way to America thanks to Hearst's International News Photo agency which not only fell for the hoax but also distributed it to all its U.S. subscribers. In the original article, the pilot's name was spelled Erich Koycher, which was a pun on the German word keuchen, meaning to puff or wheeze.
