Klaus Hill designed the Manta Fledglings. When Manta made the Fledgling-II, Klaus was not happy with the results, so he did it better: this was the Voyager.
Klaus combined the Kasper wingtip gates and Fledgling rudders to make effective NASA winglets for the Fledgling hang glider.
Klaus Hill was killed on 10 October 1978 while testing the Voyager, a hang glider of his own design, which he had just motorised.
