This unusual war story, scanned from Harvey’s Fighting Fronts #2 (1952), is based on a real-life incident. In 1948 Captain Thomas Mantell of the Kentucky Air National Guard was flying out of Goodman Field at Fort Knox, Kentucky. He became involved in the pursuit of a large airborne object, and died when his P-51 Mustang crashed. The story lives on in UFO/flying saucer literature, including this 1950 book, The Flying Saucers Are Real by Donald Kehoe.
The story is transferred to Korea and the pilot’s name is changed for this story, but it is loosely based on the same event. Here is a link to the Wikipedia entry on the Mantell Incident.
