To all,

Stephane Boisvert has very kindly re-instated, to YouTube, his video of ground testing of harness and hang strap:-
https://www.youtube.com/watch?v=aYlG8nIpiHY

It shows that it will keep the pilot in the correct position with a forward CG during flight with full control and without overloading the pilot's stamina. From a casual view point it would not be noticeable to offend the purists but would add greatly to the safety and possible duration of future flights.

Take off and landing still has to be trialled but if they can be achieved I think it is the way to go for anyone contemplating flying a replica.

4. Taking Wing: Archaeopteryx and the Evolution of Bird Flight
By Pat Shipman Published Simon and Shuster 1999.

On August 9, 1896, Lilienthal crashed as he was experimenting with a glider with a moveable elevator. A gust of wind thrust his wings up in front; although he shifted his weight forward to get the nose down, the glider simply side slipped and plummeted to the ground

5. How It Works: Science and Technology
edited by Marshall Cavendish Corporation Staff

German inventor Otto Lilienthal continued the development of gliders, making more than 2000 successful flights between 1891 and 1896. Lilienthal controlled his gliders by shifting his weight from side to side. At the time of his fatal crash in 1896, Lilienthal was working on a body harness attached to a rear elevator.

John Paul Andrews - 1944 - ‎Snippet view - ‎More editions
Thus it was that Otto Lilienthal became the first man to understand flight, to master the art himself, and to pass the knowledge along ... His initial effort to improve the hang glider brought the addition of a movable elevator to one of his last ships.

his gliders had cambered wings and fixed tail surfaces. The last glider he built had movable elevators on the tail.

8. Modernist Avant-garde Aesthetics and Contemporary Military Technology ...
By Ryan Bishop, John Phillips Edinburgh University Press 2010

In efforts of his own to carry out the necessarty flying experiments, Lilienthal devised a movable elevator that was attached to his head in order to free hi\s legs. While Lilienthat was testing this device, something failed; he fell 50 feet and died the next day.

9. Martyrs of the Air by Corley McDarment in Popular Mechanics Jan 1931

On Aug 10, 1896 Otto Lilienthal was flying his glider in a strong wind. He had a line from his elevators to his head, but in a sudden gust of wind, he apparently failed to work his head properly and the glider came down, nose on and killed the flyer. ……..his death pointed out that a better elevator control was necessary.

10. Fixed Wings: Glidershttp://learn.fi.edu/wright/again ... rs-01.html
A drawback to Lilienthal's gliders was that a great deal of control was dependent upon movements of his body. To reduce these requirements he devised a movable elevator that was attached to his head, thus freeing his legs. It was while testing this device when something failed. Lilienthal fell fifty feet and died the following day, but his achievements had attracted worldwide attention.
