It tells you there must be finite areas where the missles reach intended tarets and you can hide.

I’d hate to have to calculate those odds. Numbers of subs, go and no go areas in the seas, depths (maximum depth unknown) and probably a whole other list of variables i can’t think of.

I do think we can rule out everyplace above sea level.

Generally, Boomers hide in deployment "boxes" - but those should be large enough to make this kind of a collision a high-odds proposition. More likely the SSBNs for the French and Royal Navies use the same underwater locations for fixing their positions based on geographic landmarks. So in this case the boomers went to those locations to get their fixes ... at the same time.
