 Moreover, the knowledge that such operations are being carried out greatly enhanced the morale of the combat aircrew faced not only with the expected hostile reaction of the enemy but with the possible danger of aircraft malfunction during long overwater flights.Air-sea rescue by flying boat or floatplane was the first method used to pick up aviators or sailors who were struggling in the water.Any other aircraft design had the additional danger of ditching in the water and requiring immediate rescue, but seaplanes could land on the water in an emergency and wait for rescue.
