A Personal History of Homebuilt Aircraft Eileen A. Bjorkman. part-time, either for
pleasure or professionally, piloting jump planes for skydivers, towing gliders into
the air, or instructing students. It's much harder to be a full-time pilot and an
engineer on the side; few businesses hire part-time engineers, although some
pilots design airplanes in their spare time. Even for a person with enough time
and talent, engineering an airplane isn't a process that goes in a straightline, from

As a member of the Experimental Aircraft Association (E. A. A. #13237), I have
been pursuing a similar design for use as an STOL private light plane. In August
of 1963 I had the pleasure of visiting Mr. Zimmerman while he was director of
aeronautical research at NASA and personally discussing the development and
flight test program of the Chance- Vought V-173, the flying test bed ... This project
represents a most remarkable and unfinished chapter in the history of aviation. I
am sure ...

The Atmotic, which was to cruise at 100 kph, was a zeppelin-like craft, under
which would be slung an iron car carrying the boilers for stream-driven propellers
on the sides of the hydrogen-filled balloon. In 1853 Sir George Cayley sent his
coachman aloft on the first manned flight in history in a fixed-wing aircraft, one of
his larger experimental gliders. After an erratic flight of several hundred feet it
settled back to earth, with the servant resigning on the spot. In 1874 a steam -

The test bed for the PIK-20E was a non-motorized sailplane called the PIK-20D.
The "D" and the Mosquito are comparable ships. When Herr Hanle and his team
created the Mosquito some ten years ago, they had no idea that his Mosquito
would someday really buzz. And buzz it does. In some 50 hours of flight (10
hours engine time, 40 hours sunpower), the project remains not only successful
but a tremendously creative and rewarding challenge. $3100 in engine, prop and

stability of a sand bed under wave actions, theoretically. They analyze over
rippled beds, by introducing Oseen approximation which enables them to
evaluate the bed shear stress distribution. In order to evaluate the nonequilibrium
