The Akaflieg Darmstadt D-28 Windspiel (English: Greyhound) was a single seat high performance sailplane designed in Germany in the early 1930s. Intended to exploit a growing understanding of thermal soaring it was small and manoeuvrable with a 12 m span; silk covered for lightness it weighed less (empty) than its pilots. It held the world straight line distance record for a time in 1934.
