The DC-6 was a scaled-down four-seat version of the six-seatCW-6. It was rolled out in February1929 and went into production in two versions, the DC-6A and DC-6B. Both versions weretype certificated on October 29, 1929.[1] The Wall Street crash that day and subsequentdepression reduced demand for the aircraft and only about 20 of each model were produced.
