(Bonus) Operation Banquet was a British Second World War plan to use every available aircraft against a German invasion in 1940 or 1941. After the Fall of France in June 1940, the British Government made urgent anti-invasion preparations as the Royal Air Force (RAF) engaged the German Luftwaffe in a struggle for air superiority in the Battle of Britain. In May 1940, the Air Ministry had realized that beyond the normal reserves of the RAF, it may be necessary to throw every serviceable aircraft into the battle. On 17 May, an Air Ministry meeting outlined ambitious plans to use various aircraft in the event of an invasion.
