Titanic's Nuclear Secret

Синопсис

It was the grandest ship ever built, but its resting place was a mystery. How was the wreck's discovery linked to the Cold War's darkest days?
It was the grandest ocean liner ever built: its final resting place the most intriguing nautical mystery of the 20th century. In 1985, Dr Robert Ballard stunned the world when he discovered the Titanic more than two miles down in the Atlantic. Few knew that when he found the great ship, Ballard was on a secret mission for the United States Navy. The Navy had sent Ballard, not to hunt Titanic, but to investigate two other deep-sea tragedies: top-secret American nuclear submarines lost in the Cold War's darkest days. Now, Dr Ballard discloses the details of those missions, how he got the Navy to agree to let him search for Titanic and how his work examining two sunken subs - the Thresher and the Scorpion - gave him the crucial knowledge he needed to find the lost ship.
