Boeing 717-200 vs. McDonnell Douglas DC-9-30

The Boeing 717-200 is a narrow-body, twin-engine jetliner designed for regional and short to medium-haul routes. Characterized by its efficiency and operational flexibility, it caters to airlines requiring a reliable and cost-effective solution for less dense routes. Developed as a part of the Boeing family, the 717-200 first entered service in 1998, marking Boeing's entry into the regional jet market. It was produced until 2006, with a focus on meeting the specific demands of regional air travel. The aircraft's production history reflects Boeing's strategy to offer a range of jetliners tailored to various market segments.

With dimensions of 37.8 meters (124.0 feet) in length and a wingspan of 28.5 meters (93.3 feet), the 717-200 is ideally sized for operations at smaller airports. It typically accommodates 110 passengers, providing a comfortable and efficient travel experience on regional journeys. Powered by two rear-mounted Rolls-Royce BR715 engines, the Boeing 717-200 delivers a total thrust of 190.0 kN (42,800 lbf). Its fuel capacity of 16,670 liters (4,404 US gallons) supports a range of 3,815 kilometers (2,060 nautical miles), making it suitable for various regional routes. The aircraft has a cruise speed of 822 km/h (511 mph).

In the competitive regional jet market, the Boeing 717-200 stands as a contender against models like the Bombardier CRJ Series and Embraer E-Jets. Its introduction provided airlines with a practical and economical option for regional networks, balancing the needs for capacity, range, and cost-efficiency. Airlines such as Delta Air Lines, Hawaiian Airlines, and QantasLink have utilized the 717-200 for its operational efficiency and adaptability. Not many 717s are still in service today. Delta is one of the last airlines to be phasing out its own fleet.

The Boeing 717-200's legacy in commercial aviation is defined by its role in regional air travel. While its production has concluded, the 717-200 continues to be recognized for its contribution to the regional aviation segment.

The McDonnel Douglas DC-9-30, a narrow-body jet airliner first introduced in 1966, stands as a significant aircraft in the evolution of commercial aviation. Designed during an era of rapid growth in air travel, the DC-9-30 was developed to meet the demands of short to medium-haul routes, offering airlines a more efficient and practical alternative to the larger jetliners of the time. The Series 30 of the DC-9 included four main sub-variants, -31, -32, -33, and -34. During its production, the -30 was by far the most popular model of the DC-9 with 585 units delivered.

This aircraft was initially developed as the Douglas DC-9, prior to August 1967 merger with McDonnell Aircraft. The DC-9-30 measures in at 36.4 meters (119.3 feet) in length. This size enabled it to operate efficiently in smaller airports and on shorter runways - a niche that was underserved at the time of its introduction. Powered by a pair of Pratt & Whitney PWJTD engines, the DC-9-30 has a total thrust output of 134.0 kN (30,000 lbf). Its fuel capacity of 13,900 liters (3,672 US gallons) gives the DC-9-30 a range of approximately 2,800 kilometers (1,512 nautical miles). This range was particularly advantageous for airlines looking to serve regional networks with an efficient and reliable jet.

The DC-9-30's typical five abreast seating layout can fit around 115 passengers, with a maximum of 127 in a high-density layout.

In its market segment, the McDonnel Douglas DC-9-30 was a key competitor to other short-haul aircraft of the era. Its introduction provided airlines with a jetliner that was not only smaller and more versatile than the larger, long-haul aircraft but also more efficient and economical for short to medium-range routes.

Airlines such as Delta Air Lines, Eastern Air Lines, and TWA were prominent operators of the DC-9-30, utilizing its capabilities to enhance their regional route networks. The aircraft's role in these fleets demonstrated its effectiveness in bridging the gap between propeller-driven airliners and larger jets, contributing significantly to the growth of regional air travel.

The McDonnel Douglas DC-9-30's production and service history highlight its importance as a practical and versatile aircraft in commercial aviation. The last DC-9 to ever be built was delivered in 1982. After its retirement, McDonnell Douglas went on to produce the MD-80 and the MD-95.
