Historical Snapshot

MD-80 / MD-90 Commercial Transports

The McDonnell Douglas MD-80 and MD-90 families of jetliners were built on the same assembly line in Long Beach, Calif.

Conceived as a stretched variant of the DC-9, the MD-80 made its first flight as the DC-9 Super 80. The MD-80 Series of twinjets, featuring many advances in technology, was certified by the Federal Aviation Administration in August 1980 and entered airline service three months later.

There were 1,191 MD-80s delivered between 1980 and 1999.

The MD-90 was an advanced midsized, medium-range airliner that was first delivered in February 1995 and entered service two months later.

The MD-90’s advanced flight deck included an electronic flight instrument system, a full flight management system, a state-of-the-art inertial reference system, and LED dot-matrix displays for engine and system monitoring.

Two versions of the MD-90 entered production, and 116 were delivered between 1995 and 2000.

The MD-95, designed to replace the DC-9-30, was launched in 1995 and was renamed the Boeing 717 after McDonnell Douglas and Boeing merged in 1997. Production of the 717 began in 1998, and on May 23, 2006, Boeing delivered the final two of the 156 717s produced.
