The Seenotdienst was a German military organization formed within the Luftwaffe to save downed airmen from emergency water landings. The Seenotdienst operated from 1935 to 1945 and was the first organized air-sea rescue service.
The German Seenotdienst operated 14 Heinkel He 59 floatplanes (like this Finnish Air Force example) as well as a variety of fast boats.
Some powerful Dornier Do 24 aircraft were captured in the Netherlands and fitted for rescue, and many more ordered.
