No. 11 Group RAF No. 11 Group was a group in the Royal Air Force for various periods in the 20th century, finally disbanding in 1996. Its most famous service was during 1940 when it defended London and the south-east against the attacks of the Luftwaffe during the Battle of Britain.
History of the Swiss Air Force The history of the Swiss Air Force began in 1914 with the establishment of an "ad hoc" force consisting of a handful of men in outdated and largely civilian aircraft. It was only in the 1930s that an effective air force was established at great cost, capable of inflicting several embarrassing defeats on the Nazi Luftwaffe in the course of an initially vigorous defence of neutral Swiss airspace. The Swiss Air Force as an autonomous military service was created in October 1936. After World War II it was renamed the Swiss Air Force and Anti-Aircraft Command ("Schweizerische Flugwaffe Kommando der Flieger und Fliegerabwehrtruppen") and in 1996 became a separate service independent from the Army, under its present name "Schweizer Luftwaffe".
