In 1964 Boeing announced the development of a new short and medium-haul aircraft, named the 737 to complement the Boeing 727. The Boeing 737 is half the size of the 727 and can carry 70 to 114 passengers. It is designed to compete with the DC-9 and the BAC-1114. Lufthansa was the first customer to purchase the Boeing 737, having signed a contract for 21 aircraft in February 1965. The 737 is a twin-engine, single-aisle, short to medium-haul aircraft. It completed its first flight on April 9, 1967. Its main competitor today is the Airbus A320.
The Boeing 737-900 is part of the Boeing 737 Next Generation series. This is the third generation derived from the 737, following the 737 Classic series (300, 400 and 500), produced since 1996 by Boeing in Renton’s Boeing factory. The Next Generation series is commonly referred to as Boeing 737NG, and is sold in four different sizes, from 110 to 210 passengers. This name is given to the Boeing 737 600, 700, 800 and 900 versions.
In April 2016, the Boeing 737 had accumulated 13,000 orders and more than 9,000 deliveries, making the Boeing B737 one of the best-selling aircraft in the world. The Boeing 737-900 had a total of 4,015 aircraft delivered in April 2012, and more than 6,000 aircraft ordered.
The main customers are Southwest Airlines, Ryanair, United Airlines, as well as American Airlines. Its first flight took place on February 9, 1997. It is a small airliner aircraft.
The Boeing 737-900’s capacity is between 180 and 215 passengers. It can carry 51.7m3 of cargo volume. Its length is 47.1 meters, with a wingspan of 35.8 meters. Its height is 12.5 meters. Its maximum range is 6,230 kilometers. Its cruising speed is 969 km/h. It has CFMI CFM56-7 engines and can reach a maximum altitude of 12,500 meters.
According to Airbus officials, Boeing had planned to launch a new medium-haul family in late 2007 to replace the 737-600/700/800/900 with technologies developed for the 777-200LR and the 787. The launch was eventually postponed to an undetermined future date.
