Sprue-ce Goose:
USS Olympia is listed online as being in the possession of Independence Seaport Museum.
Is the hull simply on loan from the US Navy or is the museum free to sell the hull for scrap?
I believe "on-loan" and they can't do anything without the Navy's permission. And I believe the Navy can take it back at any time if they don't think it is being properly taken care of. Of course all they would probably do is scrap it, or more likely sink it. But it wouldn't be allowed to just sit and rust in place.
