The LF-107 Luňák (Kite) is a Czech aerobatic glider developed in the late 1940s. The LF-107 was the initial production version of which 75 were built. A simpler version (VT-7) was produced for the Czechoslovak military and the later XLF-207 Laminar was the first glider in the world with a laminar flow wing. Its maiden flight took place in Prague - Letňany (LKLT) in August 1951. This LF-107 gave a very nice display at the 'Jindřichův Hradec Airfield - Your gateway to heaven' air show.
