The Disappearance of Flight 412 is a 1974 American made-for-television science fiction drama film starring Glenn Ford, Bradford Dillman, David Soul and Guy Stockwell.

The crew is taken to a barracks building to undergo an 18-hour debriefing by members of a military Special Investigation Division (SID) team, which is more like an indoctrination to convince them that they did not see a UFO.

Just as the government interrogation begins to raise doubts among the flight crew about the "flying saucer" sighting, Moore and Dunning find the secret base.

After their release, when Dunning and Podryski choose to accept the report, the others: Moore, Bishop, Ferguson, and Riggs seek the help of General Enright (Kent Smith).

The film starts out with stock black-and-white clips of UFOs in flight and various individuals reporting sightings in newsreel style, with narrator voice-overs, to set the mood.

However, the remainder of the film (in color) deals only briefly with the fictitious UFO encounter by the aircrew, focusing instead on their ordeal as they undergo an arduous debriefing and brainwashing (perhaps better described as gaslighting) at the hands of their somewhat mysterious captors.
