A series of planes have been mysteriously shot down by a rogue pilot in a black plane with an X painted on the wing. Three of the planes were manufactured by Henry Goering and the government sends a pilot (Jerry Blackwood) to check if the planes malfunctioned due to construction, but after a survivor names a Pilot X as the murderer, Dr. Norris (psychologist) suggests a former WWI ace pilot would be the culprit due to the skill and mentality for such crimes. Goering invites 5 former WWI aces to his home to weed out the killer, while making them believe they are actually hunting for Pilot X, who kills two of the pilots and dupes Blackwood into killing the third. After that murder (and Dr. Norris after he discovers the killer's identity), Blackwood dares Pilot X to challenge him solo in the air, while the authorities are led to believe Blackwood is the culprit. Interesting premise, but this movie lies in the turkey category by the ridiculous and implausible script, really really bad acting, and horrendous directing. The climax of the final aerial battle with Blackwood and Pilot X is decent at best considering it drags on a bit longer than it should have. Avoid this one. Rating, 2.
