| The Boeing 377 Stratocruiser was the commercial version of the C-97 Stratofreighter. The two- level 377 was pressurized and could accommodate 50 to 100 passengers. On long flights the aircraft could accommodate 28 upper and lower bunk units. This led to the aircraft being referred to as the “Flying Hotel”. The 377 was larger and could fly further than the Constellation or the DC- 6 but the engines and complexity of the aircraft proved to be too costly to operate bringing production to an end in 1950. In March 1946 Northwest Airlines was the 4th Boeing 377 Stratocruiser customer with an order for 10 model 377-10-30 aircraft. All planes had Hamilton Standard propellers and rectangular windows. N74606 was c/n 15952 and was delivered in 1949 with the name “Washington” and 706 fleet number. That same year NWA was the first airline to offer cocktail service on Continental U.S. flights. Later the airline offered in-flight fashion shows and in 1959 placed an electric organ on one aircraft to provide entertainment for the passengers. NWA lost two 377’s, one to a crash and the other to a ground fire. In 1959 the 377’s were being phased out to make room for 14 new DC-7C. The last NWA Boeing 377 flight was on September 15, 1960. The remaining 8 Boeing 377’s were traded to Lockheed in exchange for a fleet of new L-188 Electras. N74606 was converted to a 377F model and eventually was scrapped.
