Take a look at the movie clip of the Silent IN with the Jet engines. I
ran some numbers on the engines over the weekend and I'm convinced
I've seen the future of soaring.

Search for a glider called "Huetter 30 TS"... (look here, for example:
http://vintagesailplanes.de/Huetter30TS.htm). First flight was in
1960.
It later became the Libelle and Salto... but it failed miserably with
the turbine engine although it was a very good glider. Noise, fuel
consumption and bad climb rates were the killer factors.
