PZL Mielec TS-8 Bies
On 23 July 1955 the first prototype was flown of a two-seat basic trainer designated P.Z.L. TS-8 and later named Bies (Fiend). A cantilever low-wing monoplane with retractable tricycle landing gear, powered by a Narkiewicz WN-3 radial engine and accommodating two in tandem beneath a jettisonable transparent canopy, initial deliveries to the Polish air force began in 1958.
The type established several class speed records, and that set on 20 May 1957, of 320.362km/h over a 2000km closed circuit, remained unbeaten until August 1982.
Built until 1962, this fully aerobatic trainer remained in service for some six years, initial deliveries of the TS-11 Iskra which replaced it in service in the Polish air force beginning in 1964.
