What is dc9-50?

The DC-9-50 is a narrow-body jet airliner produced by McDonnell Douglas from 1975 to 1982. It is the last and largest aircraft in the DC-9 family, with a longer fuselage and increased seating capacity compared to previous models. The DC-9-50 can carry up to 139 passengers with a range of 1,675 nautical miles. It was popular among regional airlines in North America and Europe due to its cost efficiency and performance capabilities. The DC-9-50 was eventually replaced by newer, more fuel-efficient aircraft such as the Boeing 737 and Airbus A320.
