The 125th anniversary of Gustav Weisskopf’s reported first powered flight has renewed the historical debate over whether the German-born inventor preceded the Wright brothers. Historical accounts suggest Weisskopf’s ‘Condor Nr. 21’ (or ‘Model 21’) took off in Bridgeport, Connecticut, on August 14, 1901, approximately two years before the Wright brothers’ 1903 flight.

While some aviation authorities, such as ‘Jane’s’, have acknowledged the possibility that Weisskopf achieved this milestone, major institutions like the Smithsonian National Air and Space Museum and the Deutsches Museum do not officially recognize the feat. Skeptics cite a lack of contemporary evidence and the fact that the aircraft disappeared shortly after the alleged flight.
