1968 was a tragic year for submariners. In addition to this loss US lost Scorpio, Israil lost Dakar and Russia lost K-129. 319 lost crew total. This is the last boat to be found. Sailors rest you oars.
I was part of a crew looking for the INS Dakar in 1997. It was not where the Israelis asked us to search for it. In a bar in Haifa, I saw our captain on the news holding up a soda can we found on the sea bed. He said if the Dakar was any bigger than that can, we would have found it.
The Dakar was found two years later in a totally different location, but I had nothing to do with it. Still, wow, those Israelis were incredibly gracious to us. One of these years, I'll head back there.
