This aircraft is the root cause of the "chute-shooting" between the Axis and Allies in Europe. Despite the fact that Britain is an island nation it was the Germans who had the best SAR system. The Luftwaffe had specialized squadrons of these SAR aircraft for locating and rescuing pilots at sea during the Battle of Britain. The RAF only had rescue launches, and grew weary of having their airmen die in the Channel while the Germans got rescued; despite being painted bright white with red crosses, the RAF started shooting down the German SAR planes. In retaliation the Luftwaffe started strafing British rescue launches and pilots in the sea or in their inflatable dinghies, and it only escalated from there.
