Pratt-Read PR-G1 / LNE-1
The Pratt-Read had two distinctions for a World War II training glider; the side-by-side seating and that it was the only training glider designed for the U.S. Navy. After release by the Navy, the LNE-1’s were acquired by the Army Air Corps which used some for a thunderstorm research project. Pratt-Read was a piano manufacturer and the G1 its only glider project. It has Schempp-Hirth type airbrakes. It won the multi-place world record for Absolute Altitude 13,489 m. / 44,255 ft. flown by Larry Edgar and H. Klieforth in 1952. One belongs to the National Soaring Museum.
Designed by M. Gluhareff, P. Leonard, J. Buxton, R. Stanley, H. Struck and R.W. Griswold, the PR-G1 has wood/ fabric wings and tail wood aft fuselage, steel-tube/ fabric forward fuselage.
This particualar airplane, N60242, crahsed about 1962 in Waimanalo, Oahu, from a low-altitude spin. Spin came from a low-altitude turn chasing a thermal in the landing approach! The pilot suffered back injuries but the ship was destroyed. Elevator and instrunments were recovered intact but everything is still in the gulch where it crashed. Pilot was a very light person and nose ballast may have been removed during a prior overhaul, as the aircraft was used to set a 71-hr aloft soaring record and all possible weight was removed to allow for supplies to be carried.

Practavia Sprite
The prototype Sprite, named the Pilot Sprite, was designed by a team at Loughborough University as a British two-seat homebuilt training or touring monoplane for amateur construction. The design had been begun as a magazine-sponsored project by Peter Garrison, who worked for Pilot at the time; when the project did not move forward rapidly enough to suit him, he returned to the United States, where he modified his design into what would become his first Melmoth.
An all-metal side-by-side low-wing cantilever monoplanes with tricycle landing gear. The Sprite was powered by a Rolls-Royce Continental O-240-A piston engine.
It was the winning entry in a competition sponsored by Pilot magazine in 1968.
Plans for amateur building were marketed by Practavia Ltd as the Practavia Sprite.
First flying in 1971, eight are known to have been built.

Poulain-Orange 1909-1910 monoplane
Gabriel Poulain moved to Berlin in 1909 and started building airplanes. The first design was an Antoinette-inspired machine. He qualified for German licence No. 14 on it in July 1910 at Johannisthal. He later teamed up with Charles Boutard and built a second monoplane with a more powerful 100 hp Argus, before moving back to France in 1911.
