David Sharp, now 75 and one of the CIA engineers behind the Glomar Explorer's attempt to raise the Soviet submarine, K-129, has been trying to write a book about the mission.
The CIA has been denying him the ability to tell his story based on "security" concerns, although most of the details of this story have been revealed already.
You may have read and seen it in Blind Man's Bluff, but there have been several documentaries about this, as well.
Hopefully, Mr. Green will get to write his book, and tell us something new about this exercise. Sounds like his angle is the engineering challenges this project faced.
