A similar thing happened when the USS Scorpion sunk. The Navy wanted to check the wreckage and recover or destroy the nuclear warheads, but without tipping-off the Soviets. So they hired Robert Ballard and had him use the cover story of searching for the Titanic. That he actually found it was a nice bonus.<p>So remember not too long ago when James Cameron made a big deal about exploring the Mariana Trench? Makes you wonder what else was down there that we won&#x27;t find out about for another 40 years.
