April 10 will mark the 50th anniversary of the loss of the the USS Thresher.
I remember when the news bulletin came on the TV. I was 9 and they still did "news bulletins" in those ancient days. Naturally I don't recall the details and I am not sure there even were many details until much later.
The Thresher was the first nuclear submarine lost at sea, but there had been many submarine disasters before that. A submarine, by nature, puts itself at risk every time it submerges, and even in peacetime they don't always come back up.
Similarly, anybody who goes off the sea in a submarine deserves just a little extra respect. The USN seems very serious about safety, and we have been fortunate that the Thresher and the USS Scorpion in 1968 have been our only two losses in the nuclear era, but we have also had some close calls. It's really a miracle, for example, that the 2005 collision of the USS San Francisco with an undersea mountain didn't result in the loss of the boat.
The USS Thresher was not saved by a miracle, however, and 129 men were lost.
