Overview
The DC-9 was designed for short, frequent flights from smaller airports, with two rear-mounted engines, a T-tail and a built-in airstair so it needed little ground equipment. It flew in 1965 and was so successful that its basic design lived on in the MD-80, MD-90 and Boeing 717.
Specifications are for the popular DC-9-30. Delta flew the last scheduled DC-9 passenger services in the United States in 2014, and almost all have now been retired.
