 In response to the heavy toll of German air action against Great Britain, Adolf Galland recommended that German pilots in trouble over the ocean make an emergency water landing in their aircraft instead of bailing out and parachuting down.The aircraft each carried an inflatable rubber raft which would help the airmen avoid hypothermia from continued immersion in the cold water, and increase the time available for rescue.British fighters such the Supermarine Spitfire and the Hawker Hurricane did not carry inflatable rafts, only lifejackets which were little help against the cold.
