Erm, are we talking about a hollywood movie or reality?

And to my knowledge, the october missile crisis has nothing to do with that movie, except submarines are the topic.

I have no idea. The more I hear the more I think the movie was referencing more real happenings than I had understood. Very early in the movie Seaman Jones (the golden ear) and rookie Beaumont are at the sonar station and Jones pulls a little training stunt. He chides the Beaumont: "like Beethoven on the computer, you have labored to produce... a biologic. ... ... A whale, Beaumont, a whale, a marine mammal that knows a hell of a lot more about sonar than you do."
