Letecké muzeum Metoděje Vlacha, Aviation museum in Mladá Boleslav, Czech Republic

Letecké muzeum Metoděje Vlacha is a museum-hangar on the northern edge of the Mladá Boleslav airfield, built in 2014 to a design by Hlaváček – architekti. The hall measures 83.2 by 44.4 metres, with a metal shell and a 22.45-metre lookout tower; inside are ten historical replicas and about 30 exhibits from the National Technical Museum and the Kbely aviation museum.

The Metoděj Vlach Foundation was set up in 2001 to collect airworthy replicas of historic aircraft, first kept in a hangar at Mladá Boleslav airport. The museum project dates from 2009, when David Rath led the Central Bohemian Region; the 150 million CZK building was completed in 2014 and opened on 12 April 2015, World Aviation and Cosmonautics Day.

The museum is named after Metoděj Vlach, a Mladá Boleslav enthusiast who built his own aircraft with an automobile engine in 1912. The Metoděj Vlach Foundation, set up in 2001, gathered airworthy replicas of historic aircraft, and these form the core of the collection. Visitors can watch Aeroclub mechanics prepare planes for flight.

Visitors can try flight simulators based on World War I biplanes or test themselves with a parachute jump simulator using full equipment. The best time to visit is in good weather when the operational aircraft are taking off from the site.

The modern building received the Building of the Year award in 2014 and its exterior shape subtly resembles the American Lockheed F-117 Nighthawk stealth fighter. This clever reference to aviation history appears throughout the structure's design.
