The Mráz M.1 Sokol (English: "Falcon") was a light aircraft built in Czechoslovakia in the years following the end of the Second World War.

Designed in secret by Zdeněk Rublič at the Beneš-Mráz factory during the German occupation, the type was put into production in 1946.

A minor variant was the Para-Sokol which was fitted with rearward sliding canopy to allow parachutists to leave the aircraft.

[2] Around 287 aircraft were built but the deterioration of the Urea-based glue used caused many examples to be condemned in the early 1960s and withdrawn from use.

[3] An M-1C, registration G-AIXN is maintained in flyable condition in the UK and is based at Turweston Aerodrome[5] Other airworthy examples exist in the Czech Republic at Prague Točná Airport (2016) and in Germany (2012).
