Wonder how much / if the Glomar Explorers chances of success could have been enhanced by the availability of GPS ...
I'm not sure. I don't think that the Russians were saying much about their sub, so I don't think they were giving away information about the location. I don't know how much difference it would have made for the Americans, once they found the sub, in the first place. And then, I don't know if GPS would have helped in regards to the problem of the sub breaking apart when they were lifting it up.
I sorta think it would not have made any difference.
With a combination of today's technologies (GPS, deep submersibles, ROVs, etc,) I would think our chances for success would be considerably improved.
