Boeing 737 Next Generation - online puzzles

The Boeing 737 Next Generation, commonly abbreviated as 737NG, is the name given to the −600/-700/-800/-900 series of the Boeing 737 airliner. It is the third generation derivative of the 737, and follows the 737 Classic (−300/-400/-500) series, which began production in the 1980s. They are short- to medium-range, narrow-body jet airliners powered by two engines. Produced since 1996 by Boeing Commercial Airplanes, the 737NG series includes four variants and can seat between 110 and 210 passengers.

As of December 2017, a total of 7,094 737NG aircraft have been ordered, of which 6,658 have been delivered. The remaining orders are in the -700, -700 BBJ, -800, -800 BBJ and -900ER variants. The 737NG's primary competition is with the Airbus A320 family. Upgraded and re-engined models in development as the 737 MAX series are eventually to supplant the 737NG, with the first 737 MAX delivered in 2017.
