Eagle Squadron

The Eagle Squadrons were three fighter squadrons of the Royal Air Force (RAF), formed with volunteer pilots from the United States during the early days of World War II (circa 1940), prior to America's entry into the war in December 1941.

Before America's entry into the War, many US recruits simply crossed the border and joined the Royal Canadian Air Force (RCAF) to learn to fly and fight. Many early recruits had originally gone to Europe to fight for Finland against the Soviets in the Winter War. Some of the recruits were men rejected by the USAAF as "lacking in intrinsic flying ability", who instead enlisted with the RCAF.

Charles Sweeny, a wealthy businessman living in London, began recruiting American citizens to fight as a US volunteer detachment in the French Air Force, echoing the Lafayette Escadrille of World War I. Following the Fall of France in 1940, a dozen of these recruits joined the RAF.

Sweeny's efforts were also coordinated in Canada by the World War I air ace Billy Bishop and the artist Clayton Knight, who formed the Clayton Knight Committee, which by the time the United States entered the war in December 1941, had processed and approved 6,700 applications from Americans to join the RCAF or RAF. Sweeny and his rich society contacts bore the cost (over $100,000) of processing and bringing the US trainees to the United Kingdom for training.

The basic requirements for those interested in joining the Eagle Squadron were a high school diploma, being between 20 and 31 years of age, eyesight that was 20/40 correctable to 20/20, and 300 hours of certified flying time. These requirements, with the exception of the flight time, were not as strict as those required for service in what was known as the U.S. Army Air Corps before late June 1941, which was a major reason why some of the pilots joined the squadron. Most Eagle Squadron pilots did not have a college education or prior military experience.
