633 Squadron

When Norwegian resistance leader Lieutenant Erik Bergman (George Chakiris) travels to Great Britain to report the location of a German V-2 rocket fuel plant, the Royal Air Force's No. 633 Squadron is assigned to destroy it, led by Wing Commander Roy Grant (Cliff Robertson). The squadron must use their fast and maneuverable de Havilland Mosquitos to bomb the cliff face in Norway until it collapses and buries the facility, a job that requires precision and bravery.
