Antonov A-13

The Antonov A-13 was a Soviet aerobatic sailplane flown in the 1950s and 1960s. It was a small, single-seat, all-metal aircraft developed from the A-11 which could optionally be fitted with that aircraft's longer-span wings. It was a mid-wing monoplane with a tadpole-like fuselage and a V-tail.

gollark: More if you compromise on quality, I suppose.
gollark: £30 of HDD capacity can store something like 90 days of music.
gollark: I would generally favour just storing music on regular digital storage (flash/tape/HDD/blu-ray/whatever), but if you want a spinny thing, CDs better, in my IMO opinion.
