Hughes intended to make a "jet-age" ''
Hell's Angels'' to the extent that the flying scenes were the most important element, and led to his obsessive re-editing that stretched into years. The lead actors fretted that the screenplay was "silly", with Wayne only taking on the role because he thought it would make a political statement, but soon realized it would become "one of the worst films" he would ever make. Wayne would later recall, "The final budget was something like four million. It was just too stupid for words." Location filming took place primarily at
Edwards Air Force Base and
Hamilton Air Force Base, California, with full cooperation from the United States Air Force. Much of the filming of flying scenes was done at Edwards using a
North American B-45 Tornado bomber as a camera aircraft.
Chuck Yeager, the first man to fly faster than the speed of sound, was assigned by the U.S. Air Force to fly for the film. Yeager would fly in the X-1, staged for the film cameras, on May 20, 1950. Another senior jet pilot who flew in the movie was USAF Major Charles Rayburn Cunningham. He and another senior jet pilot, USAF Ret Lt. Col Glen M. "Johnny" Johnson, flew for John Wayne and Janet Leigh. The
F-86A Sabre jets depicted in the early sequences were actual operational aircraft of the
94th Fighter Squadron, the first unit so equipped in the USAF, shortly after their conversion to the type in 1949. Yeager would also fly the F-86A in a series of aerobatic maneuvers, under the direction of "air boss"
Paul Mantz who coordinated the aerial sequences. Location filming for the Soviet air base was done at
George Air Force Base, a World War II air base with many of its wartime structures still intact, giving the base a primitive appearance. The 94th FS and its parent
1st Fighter Group were actually based at George during filming, and had just finished a deployment to
Ladd Air Force Base,
Alaska, as depicted in the storyline. The "Soviet
parasite fighter" that Shannon flies is actually a
Bell X-1, the first
supersonic aircraft design in the world. The "
Yak-12" at the film's beginning is a black-painted
Lockheed T-33 Shooting Star. The "mother ship" for the Soviet parasite fighter is actually a
Boeing B-50, a development of the B-29. ; The black fighter that appears near the finale, taxiing on the parking ramp and behind the "mother ship" is a
Northrop F-89 Scorpion. An F-86 Sabre is used to depict a Russian
chase aircraft, painted in dark colors,
high visibility orange, and gray juxtaposed to obscure its actual silhouette. The unpainted fighter that Olga is to test fly is also a Northrop F-89 Scorpion. John Wayne's character and other characters wear both the original Army Air Forces uniform and the newer
USAF blue uniform. ==Reception==
