In1943 he joined 333 Norwegian Squadron as a flight mechanic engineer for Mosquito aircraft at bases in Scotland. After training as an air gunner school in England and Ireland, he flew Catalinas with the squadron as a flight mechanic/air gunner on convoy duty and submarine patrols.

Following the War, Nils trained in England on aircraft engines, then instructed for the Royal Norwegian Air Force. Leaving the air force in 1947, he flew as a flight engineer with a Norwegian company and also served as a station engineer for the airline at Schipol Airport in Amsterdam, flying and maintaining Douglas DC-3 and DC-4 aircraft.

In 1951 Nils emigrated to Canada, and was employed by de Havilland Canada. His first job was converting Lancaster bombers to air sea rescue by upgrading engines. In 1952 he was hired by Sault Airways Limited in Sault Ste. Marie, Ontario. For the next four years, Nils worked there as Chief of Maintenance, servicing Norseman, Cessna, Piper, Stinson and Seabee aircraft used in bush flying operations. He earned his Aircraft Maintenance Engineer (AME) license during that time.

In 1956 he moved to British Columbia to be Chief of Maintenance for the Victoria Flying Club. There he serviced club aircraft, as well as on Harvards and Beech 18s maintained by the club for the Royal Canadian Naval Air Reserve Squadron VC 922. On March 28, 1957, Nils became a Canadian citizen at ceremonies held in Victoria.

In 1959 Nils joined Forest Industries Flying Tankers as Director of Maintenance and Chief Flight Engineer on the Martin Mars water bombers. In 1965 he joined Fairey Aviation, doing overhauls and maintenance on Catalinas, Beechcraft, Harvards and DC-3s. He also worked at converting Cansos, Avengers, Mitchells and Junkers to water bombers.
