DOUGLAS
DC-7C
Overview:
The DC-7 was developed in
response to an American Airlines request for an aircraft that would
be superior to the 'Super Connie' used by TWA. Douglas decided to
use a lengthened DC-6B to develop the DC-7. The DC-6B was stretched
3 ft. 4 in. to allow an additional row of seats on the DC-7. The
DC-7 was equipped with much more powerful engines that enabled the
gross weight to be increased by 15,200 pounds. The DC-7B and DC-7C
mainly improved fuel capacity and range; however, the DC-7C was
stretched another 3 feet 4 inches. The DC-7 is remembered as one of
the airplanes that represented the pinnacle of piston-powered
commercial transports.
