Housed in the former Bourget air terminal, built in 1914 for military purposes, this museum showcases the great successes of aeronautics and some extraordinary flying machines. In the former terminal, a jewel of Art Deco, the hangars and on the tarmac, admire examples of the spirit of aviation from Leonardo da Vinci's projects to the conquest of space (life-size Ariane 5 rocket), the first hot-air balloons developed by the Montgolfier brothers, the air force's Mirage jets and even Concorde.
