Captain Midnight (later rebranded on television as Jet Jackson, Flying Commando) is a U.S. adventure franchise first broadcast as a radio serial from 1938 to 1949. Sponsored by the Skelly Oil Company, the radio program was the creation of radio scripters Wilfred G. Moore and Robert M. Burtt, who had previously scored a success for Skelly with their boy pilot adventure serial The Air Adventures of Jimmie Allen.
Developed at the Blackett, Sample and Hummert advertising agency in Chicago, Captain Midnight began as a syndicated show in 1938, airing through the spring of 1940 on a few Midwest stations, including Chicago's WGN. In 1940, Ovaltine, a product of The Wander Company, took over sponsorship. With Pierre Andre as announcer, the series was then heard nationally on the Mutual Radio Network where it remained until 1942. It moved to the Merchandise Mart and the NBC Blue Network in September 1942. When the U.S. Government broke up the NBC Red and Blue Networks, Ovaltine moved the series back to Mutual, beginning September 1945, and it remained there until December, 1949.
The title character, originally Captain Jim "Red" Albright, was a World War I U. S. Army pilot. His Captain Midnight code name was given by a general who sent him on a high-risk mission from which he returned at the stroke of 12. When the show began in 1938, Albright was a private aviator who helped people, but his situation changed in 1940. When the show was taken over by Ovaltine, the origin story explained how Albright was recruited to head the Secret Squadron, an aviation-oriented paramilitary organization fighting sabotage and espionage during the period prior to the United States' entry into World War II. The Secret Squadron acted both within and outside the United States.
When the United States was attacked at Pearl Harbor, which curiously was foreshadowed in the program, the show shifted the Secret Squadron's duties to fight the more unconventional aspects of the war. Besides the stock villain, Ivan Shark, the war years introduced Axis villains, Baron von Karp, Admiral Himakito and von Schrecker. The Secret Squadron wartime activities were usually outside the continental United States, with adventures in Europe, South America, the Pacific, and continental Asia. War related subject matter included the theft of an experimental Flying Wing aircraft, radar coupled antiaircraft guns, jet aircraft and other weapons.
After the war, some of the newer villains used war surplus equipment to carry out their activities. Secret Squadron activities shifted to contending with criminals as well as spies. The action continued to operate internationally, with adventures in South America and Africa as well as within the United States.
The show was extremely popular, with an audience in the millions. Just under half the listeners were adult, and it was a favorite of WWII U.S Army Air Corps crews (U.S. Air Force) when they were stationed in the U.S. Radio premiums offered by the series (usually marked with his personal symbol of a winged clock with the hands pointing to midnight) included decoders, and these Code-O-Graphs were used by listeners to decipher encrypted messages previewing the next day's episode, usually broadcast once a week. Other premiums included rings, telescopes, and WWII items. (The broadcast messages were encrypted with relatively trivial monoalphabetic substitution ciphers with word division.)
The scripts depicted women who were treated as equals, not just characters waiting to be rescued. Both Joyce Ryan of the Secret Squadron and Fury Shark, daughter of villain Ivan Shark, pulled their own weight in the adventures. Joyce went on commando raids and became involved in aerial dogfights during World War II.
Major characters 
- Captain Midnight -- World War I aviator who leads the Secret Squadron, though he spends much time in the field actively contending with crime, espionage, and sabotage. Extremely skilled aviator with an ability to fly almost any aircraft superlatively. He is usually accompanied by a team consisting of three Secret Squadron members played by Ed Prentiss, Bill Bouchey and Paul Barnes with Prentiss playing the part the longest.
- Chuck Ramsay -- Captain Midnight's ward, a young man in his late teens or early twenties who is a Secret Squadron agent. Prior to the formation of the Secret Squadron, he shared adventures with his guardian. A member of Captain Midnight's usual team, he was played by Jules Getlin, Dolph Nelson, Billy Rose, Jack Bivans and Johnny Coons.
- Ichabod "Ikky" Mudd -- The Secret Squadron's Chief Mechanic. Mudd knew Captain Midnight briefly before the Secret Squadron was formed, and joined the Squadron shortly after it was formed. A member of Captain Midnight's usual team played by Hugh Studebaker, Sherman Marks and Art Hern, he was responsible for the development of the Code-O-Graph and also developed some weapons before and during World war II.
- Joyce Ryan -- A young woman in her late teens or early twenties who is a Secret Squadron agent. She was originally discovered as an amnesiac by Captain Midnight and Chuck Ramsay during a 1941 skirmish with the forces of Ivan Shark. She became a Secret Squadron member after several adventures with Captain Midnight, Chuck Ramsay, and Ichabod Mudd, replacing an earlier female companion named Patsy Donovan. Prior to World War II, she regained her memory and elected to remain in the Secret Squadron. A member of Captain Midnight's usual team, she was played by Marilou Neumayer and Angeline Orr.
- Agent Kelly, SS-11 -- Lyle William Kelly, a Secret Squadron agent who frequently accompanied Captain Midnight's usual team on their adventures. Kelly was Captain Midnight's usual contact to his superior, Major Barry Steele. Kelly was played by Olan Soule.
- Major Barry Steele -- U. S. Army Intelligence officer who was recalled from inactive duty as Captain Midnight's superior officer. Steele usually worked in the background but often provided the Secret Squadron with data and equipment. He often provided assignments for the Secret Squadron but left its administration to Captain Midnight.
- "Mr. Jones" -- Pseudonym used by the mysterious highly-placed government official who created the Secret Squadron and made Captain Midnight its commander, implicitly the President of the United States.
- Ivan Shark -- Ruthless criminal mastermind who developed a highly efficient mercenary organization. Shark often sold services of his organization to agents of foreign governments. Played by Boris Aplon, he was the default villain on the radio program, and although he was captured or thought killed many times, he always returned to plague the hero until, in the final episode, he was eaten by a polar bear while Captain Midnight watched from a plane overhead.
- Fury Shark -- Ivan Shark's devoted daughter and sadistic second in command in his organization. She frequently took command when Ivan Shark was unable to function (e.g., in prison). Highly intelligent, she always proved herself capable. She was played by Rene Rodier and Sharon Grainger.
- Gardo -- One of Ivan Shark's principal aides. Gardo was portrayed as being loyal, but relatively slow witted, and frequently the butt of Shark's wrath. Occasionally acted as Ivan Shark's pilot.
- Fang -- One of Ivan Shark's pre-war aides, Fang was an Oriental, who always addressed Shark as "Master." His presence vanished after World War II.
- The Barracuda -- Head of an extensive criminal organization similar to Ivan Shark's, but headquartered in the Orient. The Barracuda headed the Tiger Tong, a Chinese gang, and had his own private air force. Killed in 1942.
- Baron von Karp -- Nazi World War II villain with whom the Secret Squadron contended, first in the United States, then in occupied Europe.
- Admiral Himakito -- Japanese officer with whom the Secret Squadron contended in the Pacific theater during World War II.
Comic strip 
A newspaper comic strip, based closely on the radio program, made its debut in 1942. The strip, bylined by "Jonwan" (Erwin L. Hess) was drawn in a style similar to that of Milton Caniff. As with the radio show, the major characters were retained, including Joyce Ryan, Chuck Ramsay, Ichabod Mudd and Major Barry Steele. The strip was released by the Chicago Sun Syndicate on June 29, 1942, and ran until the late 1940s. The strip had some differences from the radio show and did not reprise the radio adventures. In the strip, Captain Midnight was referred to as "an unofficial fighter for freedom," which is at variance from the radio show, where the Secret Squadron was set up by a high governmental official ("Mr. Jones"), which the hero was recruited to head. Even with the variants, it was far closer to the radio show than any of the other spinoffs.
Comic book 
After Dell in 1941, Fawcett published Captain Midnight from JUN/42 to SEPT/48. The Fawcett character bore little resemblance to the radio character, and only the character  Ichabod Mudd, appeared regularly in the comic, as the sidekickSgt. Twilight.
Captain Midnight in the comic had a skintight scarlet suit and an array of gizmos like Dr. Mid-Nite which released clouds of blinding darkness, the infra-red "Doom-Beam Torch" which he used to burn his emblem into walls and unlucky villains, and a "Gliderchute" (similar to the flying Wingsuit) attached to the sides of his costume
In his Captain Albright secret identity he was a genius-level inventor like Edison. He had a secret laboratory in the desert. Otto Binder was one of the writers on the comic book.
In 2010, Moonstone Publishing's revival of the 1940s title "Air Fighters Comics" published its issue #1, which included a new Captain Midnight story.
In 2012, Dark Horse reintroduced the character.
Television and films 
- Columbia Pictures serial (1942)
Popular actor-stunt man Dave O'Brien had the title role in the Columbia Pictures 15-episode serial Captain Midnight (1942). The serial used some of the characters from the radio show, but differed significantly from the radio program. Missing were the Secret Squadron and the Squadron equipment. The Captain Midnight character was presented as a masked secret identity for Captain Albright.
- Screen Gems series (1954-1956)
The Captain Midnight TV series, produced by Screen Gems and starring Richard Webb, began September 9, 1954, on CBS, continuing for 39 episodes until January 21, 1956. In the television program, Captain Midnight (Now a veteran of the Korean War) heads the Secret Squadron as a private organization, in contrast to the radio show. As with the Fawcett comic, the only other character of the radio show held over was Ichabod Mudd (played by Sid Melton), who was used for comic relief. Another regular character was Dr. Aristotle "Tut" Jones, Midnight's resident scientist, played by character actor Olan Soule. (Soule was the only actor to perform in both the radio program and the television program. In the radio program, he played Agent Kelly, SS-11.)
The aircraft featured in the series is the Douglas D-558-2 Skyrocket, named the Silver Dart, and was based on using both models and occasionally stock footage. The series filmed at the Ray Corrigan Ranch in Simi Valley, California. When the TV series went into syndication in 1958, Ovaltine was no longer the sponsor. However, The Wander Company owned the rights to the character's name "Captain Midnight", forcing a title change by Screen Gems from Captain Midnight to Jet Jackson, Flying Commando, and all references in the episodes to Captain Midnight were redubbed (rather poorly) "Jet Jackson".
In 2010, Moonstone Books published a collection of new Captain Midnight short stories entitled Captain Midnight Chronicles. The book's stories reflect an amalgamated version of the Captain Midnight character and his supporting cast, and incorporate elements from the various media incarnations of the character, including the radio and television series, the Columbia movie serial and Fawcett comic book.
