On September 12, 1940, He 115 S4+BK of 2./506 left Tromsö seaplane station for the inhospitable Norwegian island of Jan Mayen to investigate why the Norwegian weather station there was no longer transmitting weather reports. On board the aircraft was Dr. Erich Etienne, chief of the German weather service in Northern Norway, and the aircraft observer, Lt. Müller. They were apparently the only two crew members that actually went ashore on the Island. It appeared that the Norwegian weather station had been mysteriously evacuated and the personnel had disappeared.
