were added to the wings of aircraft to stop accidental attacks on Swiss aircraft by Allied aircraft. From 1943 Switzerland shot down American and British aircraft, mainly bombers, overflying Switzerland during World War II: six by Swiss air force fighters and nine by flak cannons, and 36 airmen were killed. On 1 October 1943 the first American bomber was shot near Bad Ragaz: Only three men survived. The officers were interned in Davos, airmen in Adelboden. The representative of the U.S. military in Bern, U.S. military attaché Barnwell R. Legge, instructed the soldiers not to flee so as to allow the U.S. Legation to coordinate their escape attempts, but the majority of the soldiers thought it was a diplomatic ruse or did not receive the instruction directly. On 1 October 1944 Switzerland housed 39,670 internees in all: 20,650 from Italy, 10,082 from Poland, 2,643 from the United States, 1,121 from the United Kingdom (including five Australians), 822 from the Soviet Union and 245 from France. In September the Office of Strategic Services (OSS) was commissioned by the U.S. supreme command to organize the escapes of 1,000 American internees, but the task was not effectively accomplished before late winter 1944/45. Soldiers who were caught after their escape from the internment camp, were often detained in the Wauwilermoos internment camp near Luzern. Official Swiss records identify 6,501 airspace violations during the course of the war, with 198 foreign aircraft landing on Swiss territory and 56 aircraft crashing there. With the threat of WW2 and the possible need for the army and civilian population to retreat into the mountains (Reduit) as proposed by General Guisan, it was clear that the army air force needed the ability to attack enemy ground forces in the mountains. To practice this Axalp was selected. After WW2 ground attack by jet aircraft was practiced at Axalp, including strafing and bombing exercises. During the Cold War, military liaison officers from western, eastern and non-aligned nations were invited to the screenings. Nowadays Axalpfliegerschiessen ("Airshow Axalp") is a performance by the Air Force for anyone interested. It is the only event where everybody may have a look at a live exercise at 1,700 m (5,600 ft) above sea level. The use of helicopter ops at high altitudes, search & rescue and firefighting demonstrations also have become a large part of the Axalp air show. Cold War After World War II, the
