The Disappearance of Flight 412 is a rather cheaply made TV movie with really bad sound that doesn't seem to make any point. If there are indeed UFOs visiting our fair planet we can't seem to ever get a handle on it with anything definitive. If they are and the government has documentation they are covering it up. Hardly anything revelatory.
Air Force Colonel Glenn Ford is in charge of a flight group in which one of his flight crews is making some radar equipment checks. They see a strange object in the sky, some Marine jets are scrambled and they disappear off the radar scope. Ford's crew is diverted to a secret base nearby his base that he does not know anything about. But with a little sleuthing he tracks down where his men are gets them out.
Quite frankly he should have dropped it right there, but he pursues it and gets himself in a ringer with General Kent Smith. The conclusion, there really isn't any.
Robert F. Lyons does the best acting job as the colonel in charge of the top secret installation, a really smarmy type. Ford does his usual professional job. But in the final analysis the only people who this film might appeal to are aviation buffs.
