 MCA had expanded by the end of World War II, but post-war recession required that Burke find supplementary income to keep his business aloft.Among other enterprises, MCA undertook the maintenance of Douglas DC-3 aircraft at RCAF Station Summerside, Prince Edward Island.In 1951, the company received a major contract with the Pinetree Project, a chain of military radar stations, that led to the airlifting of over 10,000 tons of equipment and over 100,000 passengers to the eastern Arctic over a span of three years.
