[4] In 1943, Colonel Greg Brandon (Christopher George), stationed at a United States Army Air Forces 8th Air Force, 103rd Bomb Group base in England, attempts to persuade superiors that a massive, co-ordinated daylight bombing raid will hasten the end of World War II.

In spite of the mission's extreme difficulty and risk, his plan is eventually put into effect against a vital enemy aircraft factory in central Germany.

An RAF Wing Commander Trafton Howard (Gary Marshal) has been assigned to Brandon's base to teach the squadron combat tactics.

As the date draws closer Brandon further antagonizes his associates, as well as his girlfriend, WAC Lieutenant Gabrielle Ames (Laraine Stephens).

Period-style maintenance shops, an operations center and a wartime-style control tower were added to re-create the fictional Steeple Bassington base.

Another crash scene was taken from Twelve O'Clock High, the famous crash-landing carried out by Paul Mantz, another of Hollywood's leading stunt pilots, and Tallman's one-time partner in Tallmantz Aviation, before his death in 1965.
