The sixth prototype of the Z-37 and was delivered in July, 1965 ( to what?) later being registered OK-UJE with flight testing carried out in the USSR. In August 1967 it was transferred to the Aviation Research Institute (VZLÚ) in Prague but sometime in 1968 was damaged by a hurricane but rebuilt using parts (wings, center plane, engine) from Z-37 cn 007, OK-UJC. It made its last flight in June, 1974, completing just over 477 hours and 2514 take-offs. It was transferred to VHÚ (Kbely museum parent organisation) in January 1975 and has been on loan to this fire-fighting museum since April 2011.

This Z-37 was built in Kunovice and first flew in September, 1968, after which it was handed over to Agrarflug, the agricultural division of Interflug. It later received the newer DDR-SNK registration and was withdrawn from service in 1984 with an extended lifetime of 7,280 hours. The aircraft was flown to the museum in April 1984 and placed on display. Due to its poor condition, it was withdrawn in 2011 and earmarked for restration. From 2021-2022, this aircraft was completely refurbished and in July 2022 rejoined the display, looking resplendent in its 1968 scheme.

Preserved outside this museum that aims to inform people about the life of Otto Liliienthal, a pioneer of early flight and gliding, who is quoted by the wright Brothers as having been a major influence. In 1893, Lilienthal also started performing gliding attempts from the hills around Stölln and the Rhinow Hills. Unfortunately, in August 1896, during one of these flights Lilienthal's glider pitched forward and he sustained fatal injuries.
