I am fascinated by the KAL 007 Conspriacy theory that it actually landed and the passengers, including Larry Mcdonald, were taken prisoner

There is actually a website, quite old, dedicated to it. This website was started by members of the families of the victims.

Curiously enough, the Soviet Union had shot down another Korean Airlines flight 5 years before, under similar circumstances and all the passengers, but 2, survived.

Link to flight 902, 5 years before flight 007

Larry Mcdonald was a well known anti communist and the second president of the John Birch Society.

We all have our own personal theories which we think are actually plausible, this one would be one of mine.
