Not to be confused with a 1942 20th Century-Fox aviation actioner with the same title, Thunderbirds is a Republic Pictures war flick. John Derek and John Barrymore Jr. play two handsome flyboys with the Oklahoma National Guard who are pressed into service at the outbreak of World War II. They spend most of the war in the Italian campaign, then blast their way into Berlin. By way of a plot complication, Ward Bond shows up as a tough veteran sergeant who turns out to be the long-lost father of hotheaded Barrymore.
