Interestingly enough, it's entirely possible that there is no water in the pool. It was behind air-tight doors, which dropped before the ship went under (which is when the water that was originally in the pool spilled out into the rest of the room). . .

They are checked periodically for radiation leaks, and to be sure other countries aren't sniffing around. These days, the threat of someone making off with a rusty old Mk 45 nuclear torpedo aren't really a concern, but back during the Cold War it was.

I would imagine that Scorpion/Thresher survey visits are good training for current generation crews on Seawolf-class et al. to brush up their skills.

The wreck of Scorpion? Tons of information about it, but a lot still classified as she carried two Mk 45 nuclear torpedoes.

Really fascinating to read about how the search area was determined and conducted, and then the investigations in to why it sank. Long story short, Bayesian search functions let them find a very small needle in a very large haystack quite quickly; the same method used after the B-52 crash at Palomares.

"Blind Mans Bluff" is a good starting point.

When Ballard and crew found the wreckage they started yelling and celebrating in the sub. Then they realized they were literally dancing on a mass grave and everyone straightened up.

What TheSchlaf said.

Rusticles (an iron eating bacteria) have weakend the iron over time, combined with currents and wear and tear from visiting submarines, escpecially those who seek to retrieve stuff from the wreckage.

Best Comprehensive Single Volume History of Spain (in English)?

I was hoping to find an overview history of Spain. There are a lot of them, and I'm not sure which one to read.
I saw quite a few in my search:

The History of Spain by Peter Pierson
Spain A Unique History by Stanley G. Payne
A Concise History of Spain by Phillips

Any thoughts or recommendations?

Hi, I know that throughout the 19th century, advances in archaeology and historical study of ancient near east and the decipherment of texts, heavily impacted questions on the historicity of the different parts of the bible. I was wondering if there are any books which tell the story of how these discoveries changed and impacted biblical studies specifically in 19th century, thanks!
