*1922 The first soaring flight of one hour in slope lift ( using hill currents ) is made by Arthur Martens in a Vampyr sailplane designed by Wolfgang Klemmperer at the Wasserkuppe, Rh�n, Germany.

By assuming the energy amount due to solar radiation it is possible to predict the 2 boundary layer of the atmosphere, the occurrence and development of clouds and the conditions for soaring flight during the day.
43.
Because the battery power is enough to launch the aircraft for a soaring flight it is theoretically possible to launch on battery power, soar while the batteries are being charged by sunlight and then continue powered flight.

As a consequence he was he also granted his gliding certificate, issued by the Association of German Model & Soaring Flight Clubs, with the serial No . 1, being the very first glider certificate ever issued worldwide.

The mission of the school was to train glider pilot students in proficiency in operation of gliders in various types of towed and soaring flight, both day and night, and in servicing of gliders in the field.

*1923 French Lieutenant Thoret makes the first soaring flight of 7 hours in a Hanriot HD-14 biplane as he flies with his engine stopped in a slope lift ( using hill-side air currents ) in Biskra, Algeria.

This soaring flight of understanding would have required decades of work, had not the main principles been brought to light over many years by those who study the development of the Drosophila fruit fly, a standard laboratory organism for biologists.

Martin Schempp returned 1929 to the USA to build German sailplane designs under license there at " Haller-Hirth Sailplanes " and to act as a soaring instructor at " Haller School Of Soaring Flight " in Pittsburgh ( Greensburg Airport ).

In May 2016, the San Diego Air and Space Museum established a new exhibit for John J . Montgomery in their main rotunda including " The Evergreen " glider from 1911 and Montgomery s original " Soaring Flight " manuscript from 1896.

Moy was one of the earliest members of the Aeronautical Society of Great Britain ( later the Royal Aeronautical Society ), founded in 1866, and presented a number of papers at its meetings, including one in 1869 describing the soaring flight of albatrosses in a wind.
