DALLAS – Today in Aviation, The prototype of the Let L-410 Turbolet (registration OK-60), then known as the XL-410, took to the skies on its maiden flight in 1969. At the controls were Let pilots Vladimir Vik and Ing. František Svinka.
The aircraft is a 15-seat, unpressurised, high-wing regional airliner powered by the Walter M601 engine. However, delays in the development of the power plant led to early models being powered by the Pratt & Whitney PT6-27 engines.
