Editing Donald Keyhoe (section)

== Writing for the pulps and glossies ==
By the time his UFO books appeared, Keyhoe was already an established author, with stories in the [[pulp magazines]] of the 1920s and 1930s. Four of his short stories were printed in ''[[Weird Tales]]'': "The Grim Passenger" (1925), "The Mystery Under the Sea" (1926), "Through the Vortex" (1926) and "The Master of Doom" (1927). He also produced the lead novel for all three issues of a short-lived magazine ''[[Dr. Yen Sin]]'': "The Mystery of the Dragon's Shadow" (May–June 1936), "The Mystery of the Golden Skull" (July–August 1936) and "The Mystery of the Singing Mummies" (September–October 1936). Dr. Sin was opposed by a hero who could not sleep.<ref>{{Cite web|url=http://www.philsp.com/data/data093.html|title = Magazine Data File}}</ref>{{fv|date=May 2025|reason=No mention of Keyhoe or Sin or any of the stories at the given reference}}

Keyhoe wrote a number of air adventure stories for ''[[Flying Aces (magazine)|Flying Aces]]'', and other magazines, and created two larger-than-life [[superhero]]es in this genre. The first of these was Captain Philip Strange, referred to as "the Brain Devil" and "the Phantom Ace of G-2." Captain Strange was an American [[intelligence officer]] during [[World War I]] who was gifted with [[Extra-sensory perception|ESP]] and other mental powers. His existence has been perpetuated beyond Keyhoe's stories as a minor member of the [[Wold Newton family|Wold Newton universe]].<ref>{{Cite web|url=http://www.herogames.com/forums/showthread.php?t=40023|title= Captain Strange, the Brain Devil!

Keyhoe's other "superpowered" flying ace was Richard Knight, a [[World War I]] veteran who was blinded in combat but gained a supernatural ability to see in the dark. Knight featured in 35 adventure stories from 1936 to 1942.<ref name="Page111">{{cite web | url=http://www.philsp.com/homeville/AFI/k00111.htm#A9 | title=Magazine Contents Lists: Page 111 }}</ref>{{fv|date=May 2025|reason=No mention of Keyhoe or Knight at the given reference}}

Other series he wrote included the "Eric Trent" series in ''Flying Aces'' and the "Vanished Legion" in ''Dare-Devil Aces'', and two long-running series: "The Devildog Squadron" in ''Sky Birds'' and "The Jailbird Flight" in ''Battle Aces''.<ref name="Page111"/>{{fv|date=May 2025|reason=No mention of Keyhoe or Trent at the given reference}}

Many of Keyhoe's stories for the pulps were science fiction or [[Weird Fantasy]], or contained a significant measure of these elements&nbsp;— a fact that was not lost on later critics of his UFO books.<ref name = "Pulp">{{Cite book |last=Hutchison |first=Don |title=The Great Pulp Heroes |year=1995 |publisher=Mosaic Press |isbn=0-88962-585-9 }}p. 188</ref>
