Military aviation proved its usefulness during the First World War, with reconnaissance aircraft and later with bombers and fighter planes. After the war, technical progress benefited civil aviation, which took off. In 1918, the Farman F.60 Goliath, derived from a heavy bomber, was transformed into a passenger aircraft. It could accommodate 12 passengers in wicker seats. Sixty aircraft were sold to the first airlines, such as Air Union in France and Sabena in Belgium. The Musée de l’Air et de l’Espace (Air and Space Museum) at Le Bourget has the only remaining Farman F.60 Goliath fuselage.
