Annual passenger revenue exceeds mail revenue for the first time. 1942 - 1944 Northwest carries out 11 major government wartime assignments, including lifeline to Alaska, bomber modification and a variety of special projects; employment leaps from 881 to 10,439. Service to several smaller cities is suspended when the government commandeers half of Northwest's fleet. Northwest receives Army- Navy "E" for operation of bomber modification center. Southern Airways applies for CAB certification to establish a local service air carrier in eight southeastern states. Wisconsin Central Airlines is incorporated with the Four Wheel Drive Automobile Company as the major shareholder.

The first flight: Minneapolis/St. Paul, to Hibbing/Chisholm, Minn., in a Lockheed Electra. All other "first day" flights are canceled due to bitter cold and widespread freezing rain and snow.
