Danish inventor Jacob Christian Hansen Ellehammer’s 1905 first full-scale attempt did not fly. Ellehammer then experimented with an upper “sail”, added it to the machine, and succeeded in making brief tethered ascensions from a circular track on September 12, 1906. Since the island of Lindholon, on which tests were carried out, was too small for a straight flight to have been attempted.
Many people acknowledge J.C.H.Ellehammer of Denmark as the first to fly in Europe because of a reported 42 m hop about 20 inches above the ground made on 12 September 1906.
Ellehammer’s work does not seem to have relied on the designs of his predecessors. He did fail to develop a workable control system. Lack of funds finally forced Ellehammer to abandon his experiments.
