Convair CV-990

The Convair 990 Coronado is a retired American narrow-body four-engined jet airliner produced between 1961 and 1963 by the Convair division of American company General Dynamics. It was a stretched version of its earlier Convair 880 produced in response to a request from American Airlines: the 990 was lengthened by 10 ft (3.0 m), which increased the number of passengers from between 88 and 110 in the 880 to between 96 and 121. This was still fewer passengers than the contemporary Boeing 707 or Douglas DC-8, although the 990 was 25–35 mph (40–56 km/h) faster than either in cruise.
