Douglas DC-9
The DC-9 is the Douglas twinjet with two Pratt & Whitney JT8D engines on the rear fuselage and a T-tail. It first flew on February 25, 1965, entered service with Delta Air Lines that December, and stayed in production at Long Beach, California, until 1982, after Douglas had merged into McDonnell Douglas in 1967. Douglas built 976, including 41 military C-9s, in stretches from the 90-seat DC-9-10 to the DC-9-30, -40 and -50. Delta flew the last scheduled DC-9 flight by a major US airline in January 2014, and the series lived on in the MD-80.
