During World War 2, both the RAF and the Luftwaffe lost a large number of pilots at sea. The British used a couple of high speed boats that patrolled the English Channel and picked up downed pilots before they were overcome by the elements. The Germans used the Heinkel He 59 float planes that could land on water, in addition to boats. The German sea rescue service, or Seenotdienst, was more successful than the Allied effort. They had bases all along the coast of Denmark, Norway, Netherlands and France, covering much of the North Sea and the Baltic Sea. They also enlisted the help of local rescue societies to increase their reach.
