Between August and November of 1903, Karl Jatho tested his large flying machine near Hannover, Germany. Reportedly, at first the machine had three lifting surfaces, which were soon reduced to two. He had patterned the unusual wing design of his aeroplane after the Zanonia seed, which was known for its ability to glide in a stable fashion. Jatho managed to make a few short hops into the air, the best of which was just under 200 feet at an altitude of about 10 feet. However, he was not satisfied with the results as he tried to extend his hops, for the single-cylinder 10 h.p. Buchet engine driving a two-bladed pusher propeller was simply inadequate. In addition, the wings of Jatho's machine were essentially flat, apparently having no curve in section, so lift was limited. The control system also appears to have been very limited in its effectiveness. Even so, it is generally conceded that Karl Jatho did manage to go aloft in a powered heavier-than-air machine. Within another six years Jatho had designed, built and flown a more robust aeroplane.
