Aleutian Islands Campaign, June 1942 - August 1943. This photograph shows one major obstacle confronting operations in the Aleutians – the weather – and one of the things U.S. Forces are doing about it. Shown: Flight Crew Works Over Craft. Using special heating apparatus, a flight crew warms up the engines of a Consolidated PBY “Catalina” flying boat, stationed on the advance American base on Adak Island. Another crewman changes spark plugs.
