Dick Schreder started a self-launched seaplane glider project back in the
1970s. I believe he was going to call it a HP-21. The project was never
finished and was donated to Penn State University (PSU) prior to his death.

The HP-21 was to be a two-place, side-by-side, self-launching, amphibious
sailplane with automatic extending and retracting engine. Design specs
called for a foam and fiberglass hull, retractable gear and wings
constructed of metal and foam (like the HP-16, RS-15 and HP-18).

Dick flew seaplanes in WW-II and was the first sinking of a U-Boat by a US
aircraft. (It is a great story. It and others can be found in the book
"10,000 Feet and Climbing - The Aviation Adventures of Richard E Schreder.)
The HP-21 was going to be an attempt to combine his love of soaring with his
love of "flying boats."

The PSU Soaring Club has what remains of the project listed in the "Trading
Post" section of http://www.soaridaho.com/Schreder.

An article about the HP-21 appeared in "Soaring" many years ago. I have a
copy and will posted on the "Schreder Designs" web site when time is
available.

OK, here's a question. Does a seaplane motoglider exist?

If someone were to make one, would it be eligible to be flown as a
motoglider, and therefore be able to have a pilot (without a medical) fly
it
legally as a motoglider?

And yes, I did Google, first. g
