On August 27, 1939, days before World War II broke out, the airspace over Germany and France was closed. Swissair was forced to suspend service to Amsterdam, Paris, and London. Two days later, Swissair service was closed completely. Of 180 employees, 131 had to serve in the army. In spite of the war, some routes were re-introduced, such as Munich, Berlin, Rome and Barcelona. In 1940, an invasion of Switzerland was feared, and Swissair moved their operations to the Magadino plains in Ticino. Operations were suspended in August 1944, when a Swissair DC-2 was destroyed in Stuttgart during an American bombing raid.
