To answer yesterday's little quiz, that aerial shot was of USS Kittiwake, a former submarine rescue vessel for the US Navy. After being decommissioned in 1994 it was sunk as an attraction for scuba divers off Seven Mile Beach, Grand Cayman in 2011. It's pretty amazing to see just how much it has changed in only 8 years. Check out earlier pictures on the web and you'll find that it used to be white! What's even more impressive is that it was sunk upright, but strong surges from tropical storm Nate pushed the wreck closer to the reef and tipped it over on its port side.
