Table 6 Notes : Douglas, Boeing (Douglas Products Division) & Lockheed Aircraft

In the early 1990's the MD-80 series was re-engined and stretched (175 seats) to give rise to the MD-90 series and later shrunk (100 seats) for the MD-95 variant. The Douglas DC10 is no longer is production having been superseded by the updated and re-engineered MD-11. This is a medium to long range (7000nm) aircraft carrying over 300 passengers. The aircraft has three engines (two wing mounted and one installed at the base of the fin). The MD-12 is a high capacity (500 seats) long range (8000nm) four-engined, double deck aircraft proposed to compete with the stretched B747 designs. As a result of the merger with Boeing MD80 and MD90 production will terminated in 2000 along with the MD11. Thus the Boeing 717 (formerly MD95) will be the only remaining Douglas product in production.

The Lockheed L1011 'Tri-Star' with a configuration similar to the DC-10 first entered service in 1972 and is no longer in production although there are still several aircraft in commercial operation.
