The Karl-Jatho-Project. Retrieved Oct. 16, 2014 by November 1903 Jatho had managed to achieve a continuous flight of at altitude, a month prior to the 17 December 1903 pioneer flights of the Wright brothers spanning distances of 37, 53, 61, and 260 meters (40–284 yards) at about altitude. Jatho eventually gave up, noting "In spite of many efforts, (I) cannot make longer or higher flights. Motor weak." With a later machine, Jatho would make successful flights in 1909 – at about at altitude. He also founded a flying school and an aircraft factory, but did not have much success.
Although in Germany some enthusiasts credit him with making the first airplane flight, according to modern researchers such as Leonhardt and Lohmann (interviewed for the 2006 NDR Fernsehen documentary ''Sorry Mister Wright'' and the 2009 documentary ''Made in Hannover – German Aviation Pioneer Karl Jatho took off ahead of Orville Wright''), Jatho's personal claim to a place in the history books of aviation on grounds of significant pioneer motorized flights of 18 meters in August and 60 meters in November 1903 prior to the Brothers Wright is tarnished by the fact that he took 30 years to have it legally certified by original eyewitness accounts.
In the summer of 1933, Jatho's former assistant Werner Hegge attempted to give practical proof by a flight demonstration with an exact replica of Jatho's original machine, but according to the 9 October 1933 issue of the local ''Hannoversche Kurier'' newspaper, the weather did not allow for a safe start on the scheduled date. From 1936 onwards, Hegge's replica became a public exhibit at the ''Deutsche Luftfahrtsammlung Berlin'' (see German Wikipedia), where it was destroyed during WWII.
In September 2006, a local initiative of aviation history researchers and replica builders led by Harald Lohmann attempted another recreation with a new replica in order to bolster credence to Jatho's original claims, but again, adverse weather conditions prevented a successful start, although the replica did achieve successful ground speed that in theory would have allowed for a lift off had it not been for the strong winds on the day of the test.See aforementioned documentaries ''Sorry Mister Wright'' (2006, by

Karl Jatho ( 3 February 1873 – 8 December 1933) was a German inventor and aviation pioneer, performer and public servant of the city of Hanover
Hanover (; german: Hannover ; nds, Hannober) is the capital and largest city of the German state of Lower Saxony. Its 535,932 (2021) inhabitants make it the 13th-largest city in Germany as well as the fourth-largest city in Northern Germany ...

Achievements and claims to precedence over the Wright brothers
From August through November 1903, Jatho made progressively longer hops (flights) in a pusher triplane, then biplane, at Vahrenwalder Heide outside of Hanover. His first flight was only at about altitude. Sources differ whether his aircraft was controlled. The earliest contemporary source suggesting that it was controlled, a newspaper article from ''Hannoverscher Courier'' dating 1 August 1907, states that Jatho "has been working on controllable air vehicles for 12 years by now", however a legal document dated 19 November 1902 (an official decline by legal authorities to attend a legal test examination that Jatho had offered to them) appears to describe a design that still lacked a controlling mechanism. 30 years after his first flight tests, four eyewitnesses gave a legal testimony certified by a civil law notary in 1933 to having observed his August 1903 flight and that the given data was correct.
