The British even shot at the Red Cross! The Red Crosses at the fuselage and wings can be seen from a large distance. Despite this the British again shot a German rescue seaplane while trying to rescue British crewmembers who made an emergency landing at high seas. A rescue seaplane of the Seenotstaffel 1 (Sea rescue squadron 1) at the start. Photo 42467, July 17, 1940.
