I like to research aircraft that you guys post, especially ones I am not familiar with.
"The Sunderland was one of the Royal Air Force's great wartime flying boats. A Sunderland flew at Windermere in 1990 but, sadly, none remain airworthy now. Arguably, an even greater flying boat was the American Consolidated Catalina, several hundred of which served around the world with the wartime Royal Air Force."
"You can see a Short Sunderland flying boat at several locations. The RAF Museum in London (Hendon) has a Sunderland MR5 on display. Additionally, a Sunderland is preserved at Fantasy of Flight in Florida. Other locations where you can potentially see Sunderland parts or remnants include MOTAT in New Zealand and potentially Pembroke Dock in Wales.
Here's a more detailed breakdown:
RAF Museum London (Hendon): The museum has a Sunderland MR5 on display, allowing visitors to view the aircraft. You can even explore inside the aircraft.
Fantasy of Flight, Florida: Wikipedia notes that a Sunderland is on display at this location.
MOTAT, New Zealand: MOTAT has a Sunderland that was gifted to them in 1966.
Pembroke Dock, Wales: While not a complete aircraft, Pembroke Dock has been a site for Sunderland preservation efforts and may have remnants or exhibits related to the aircraft, according to the British Pathe."
