Boeing 717-200 vs. Douglas DC-8

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 Douglas DC-8, is a long-range, narrow-body jet airliner developed by American Douglas Aircraft Company. Introduced in the mid-1960s, the DC-8 was among the first generation of commercial jetliners, marking a significant transition in air travel from propeller-driven to jet-powered aircraft. This model was developed during a period of rapid advancement in aviation technology, driven by the growing demand for faster and more efficient air travel.

The DC-8's design features a length of 57.1 meters (187.3 feet), which, at the time of its introduction, was one of the longest for any airliner. This length, coupled with a wingspan of 45.2 meters (148.4 feet), reflects the aircraft's capacity to handle long-haul routes, a key requirement during the jet age's early years. The DC-8's size was a response to the airline industry's needs for greater passenger capacity and range. Equipped with four Pratt & Whitney JT3D turbojet engines, the DC-8 could achieve a total thrust of 320.0 kN (36,000 lbf). This power output was instrumental in enabling the aircraft to reach a range of approximately 5,900 kilometers (3,186 nautical miles), making it suitable for transcontinental and transatlantic routes. The DC-8's speed and range capabilities were significant advancements at the time, contributing to the reduction of travel times on international routes.

The cabin of the DC-8 was designed to seat around 220 passengers in a typical two-class configuration with six seats across. This capacity allowed airlines to transport more passengers per flight compared to earlier propeller-driven airliners, significantly increasing operational efficiency. The interior of the DC-8 was designed with comfort in mind, offering features that were considered state-of-the-art during its era.

In the commercial aviation market, the Douglas DC-8 competed with the other early quadjet, the Boeing 707. The introduction of the DC-8 was part of the broader trend towards jet-powered air travel, which revolutionized the airline industry by offering faster and more comfortable flights over longer distances. Airlines that operated the DC-8 were United Airlines, Delta Air Lines, Thai Airways, and Pan American World Airways. The DC-8's operational role was marked by its ability to serve long-haul routes with improved efficiency and speed, a factor that contributed significantly to the growth of global air travel during the 1960s and 1970s. The DC-8 was produced until 1972, with 556 aircraft built. As the model aged out, it was superseded by larger wide-body Douglas' DC-10 trijet.
