Rolladen-Schneider LS5

The Rolladen-Schneider LS5 was an Open Class single seat glider aircraft designed by Rolladen-Schneider. Only a single unit was built.

The LS5 was announced in 1980 as Rolladen-Schneider’s entry into the exclusive Open Class. The economic viability of the design was compromised, however, with the arrival in 1981 of the Schempp-Hirth Nimbus-3 and the Schleicher ASW 22, both of which outclassed the predicted performance of the yet-to-fly LS5. Although the moulds had already been completed, Rolladen-Schneider decided not to pursue further development. Klaus Mies from Kaiserslautern used these moulds to produce one glider of the type. This homebuilt prototype made its maiden flight in 1988, receiving the registration number D-7742. It is based at Marpingen in Germany.

gollark: You don't actually need simple shapes very badly as long as you have an algorithm which is not likely to be biased.
gollark: Okay, rearrange the states so they're square.
gollark: A simple if slightly inaccurate way would be some kind of binary space partitioning thing, where (pretending the US is a perfect square) you just repeatedly divide it in half (alternatingly vertically/horizontally), but stop dividing a particular subregion when population goes below some target number.
gollark: The more complex the algorithm the more people might try and manipulate it. The obvious* solution is to just split up the country by latitude/longitude grid squares.
gollark: The Netherlands will just conquer all of the areas "lost" to rising sea levels.
