A Yank in the R.A.F. is a 1941 American war drama film directed by Henry King and starring Tyrone Power, Betty Grable and John Sutton. Released three months before the attack on Pearl Harbor plunged the United States into World War II, it is considered a typical early-World War II production. Originally titled The Eagle Squadron, it is based on a story by "Melville Crossman", the pen name for 20th Century Fox studio chief Darryl F. Zanuck. It follows an American pilot who joins the Royal Air Force (RAF), during a period when the United States was still neutral.
