The McDonnell Douglas MD-82 is a twin-engine, single-aisle jet airliner that was developed from the earlier MD-80 series. It features a T-tail design and is known for its efficiency and reliability, making it a popular choice for airlines during the 1980s and 1990s. The aircraft typically seats around 130 passengers and has a range of approximately 2,500 miles. The MD-82 is powered by two Pratt & Whitney JT8D engines, which contribute to its performance and fuel efficiency. It was widely used by various airlines, including American Airlines and Alaska Airlines, before being gradually replaced by newer models like the Boeing 737 and Airbus A320.
