Letany leteck Rosika Bohumil (2021)

The area between Letany, Kbely and akovice became a magical triangle of aviations rapid development soon after the founding of Czechoslovakia. Several aircraft companies and two factory airfields were established there, and the great majority of Czechoslovak aircraft were created or test-flown there. It also produced many designers who influenced the development and construction of aircraft in the country for six decades.
