I have a soft spot for seaplanes. The Sunderlands flew out of Pembroke Dock in West Wales during World War II, protecting convoys and hunting German submarines in the Atlantic and Irish Sea.
They apparently had a very distinctive sound to their engines, something that my grandpa likes to reminisce about.
Although the "source" is the Daily Mail (I apologise) the content itself is quite interesting, concerning the location and partial raising of one of the Sunderlands that was ditched during the war, amazingly the location directed by a member of that very air crew: http://www.dailymail.co.uk/news/article-2523196/WWII-Sunderl...
