Boeing 727-200 vs. McDonnell Douglas DC-9-30

The Boeing 727-200 is a narrow-body, trijet airliner that played a significant role in the expansion of commercial air travel. First introduced in 1967, the 727 was designed for short to medium-haul routes.

The -200 variant of the Boeing 727 measures in at 153.1 feet (46.7 meters) long, with a wingspan of 108.0 feet (32.9 meters). This size makes it well-suited for operations at regional and domestic airports. The aircraft typically accommodates 145 passengers. In a two class-configuration, first class has 4 seats abreast, with a 3-3 seating layout in the back. Sporting three engines, the 727-200 delivers a total thrust of 45,000 lbf (201.0 kN). It has a fuel capacity of 8,084 US gallons (30,600 liters), supporting a range of 1,890 nautical miles (3,500 kilometers). With a cruise speed of 537 mph (865 km/h), the 727-200 was known for its ability to efficiently cover distances within its operational scope.

In the commercial aviation market, the Boeing 727-200 competed with aircraft like the Douglas DC-9 and the early Airbus A320 series. Its trijet configuration was unique for its time, offering an optimal balance of performance and efficiency for short and medium-haul flights. Major US-based airlines such as American Airlines, Delta Air Lines, and United Airlines all operated the Boeing 727-200. The trijet was also a part of a fleet for Iberia, Lufthansa, All Nippon Airways, and Air France.

The Boeing 727-200's development and introduction into the market were indicative of the era's aviation trends, focusing on creating more efficient and versatile aircraft for a growing industry. Its production history reflects Boeing's ability to innovate and adapt to changing airline needs, particularly in the regional and short-haul segments. The Boeing 727-200 is no longer in production, and very few our left in commercial aviation. The aircraft's contribution to the expansion of regional air travel is very notable, showcasing the evolution of aircraft design and technology to meet the demands of an increasingly connected world.

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.
