Jud Taylor directed this TV movie that stars Glenn Ford as Colonel Pete Moore, in charge of the Whitney Radar Test Group that has sent a four-man crew on flight 412 to investigate electrical difficulties, but instead encounters what may either be a blip, or a UFO, but after they are interrogated by a mysterious military intelligence team(led by Guy Stockwell) that does not want to hear about "science fiction", the men find themselves uncomfortably at odds with their own government. Can Col. Moore get to the bottom of this matter, save his crew and all their careers? Reasonably good film defies its low budget and brief running time to tell a well-acted and tense narrative that doesn't provide easy answers, but instead unfolds in a matter-of-fact way, which is most effective. Also stars Bradford Dillman, David Soul, Robert F. Lyons, and Kent Smith.
