A total of 18 metres was the distance covered by Karl Jatho during his initial flight attempt at the Vahrenwalder Heide in August 1903. This achievement utilized a pusher triplane design, marking the beginning of a series of experiments in Hanover that Jatho claimed preceded the motorized aviation breakthroughs of the Wright brothers later that same year.
Aviation Experiments
Between August and November 1903, Jatho conducted motorized flight trials using both triplane and biplane configurations. His first recorded hop occurred at an altitude of approximately one metre. By November, his technical notes and subsequent analysis by historian Wolfgang Leonhardt indicate he attained a continuous flight of 60 metres at an altitude of 2.5 metres. Despite these figures, Jatho eventually identified a lack of motor power as the primary constraint preventing sustained altitude or increased distance, leading him to temporarily abandon the project.

The validity of Jatho's claims regarding priority in flight remains a subject of modern research. While a 1907 article in the Hannoverscher Courier suggested he had been developing controlled air vehicles for 12 years, earlier 1902 legal documents regarding a requested test examination described designs that lacked a steering mechanism. The documentation supporting his 1903 success largely relies on testimonies certified 30 years later by four witnesses. Researchers like Leonhardt and Lohmann note that this significant delay in official legal verification has complicated the academic acceptance of his place in the history of early aviation.
Later Career and Historical Recreation
In 1909, Jatho returned to aviation with a new machine, achieving flights of 60 metres at altitudes reaching 4 metres. He founded an aircraft factory and a flying school, though these ventures saw limited commercial success. Decades later, efforts to validate his work through physical replicas encountered practical obstacles. An attempt by Werner Hegge in 1933 was thwarted by poor weather conditions, and a 2006 project led by Harald Lohmann similarly failed to achieve a liftoff. The latter replica was ultimately transferred to the World of Aviation exhibition at Hannover Airport rather than undergoing further flight testing.

Questions readers ask
Did Karl Jatho fly before the Wright brothers?
He achieved motorized hops in August and November 1903, but the control mechanisms of his machines and the timing of his documented success remain a point of historical contention.
What happened to his flying machines?
A replica built by Werner Hegge was destroyed during World War II, and a 2006 replica is kept as a static exhibit at the Hannover Airport.
