Ship 717 is the only surviving Delta DC-7 and highlights the spectacular closing act of the airline's propeller era.
Ship 717, N4887C, delivered on November 27, 1957, was the sixth DC-7B to become part of Delta's fleet. One of 21 DC-7/7Bs, Ship 717 would have flown routes southbound between Chicago, Cincinnati, Atlanta and Miami; northbound, from Miami and Atlanta and Chicago; and from Chicago to Houston and St. Louis.
DC-7 service also included San Juan and Caracas from New Orleans; and to Washington, DC and New York from Atlanta, Houston and Dallas. By 1958, Delta's DC-7 and DC-7B fleet served 18 major cities and accounted for 53% of all Delta seat miles flown.
Transcontinental service to California began in 1961.
DC-7Bs were the last piston-driven aircraft Delta purchased for passenger service. Douglas DC-8 jet service began in 1959 and the last of the DC-7 fleet was retired by 1968.
