Tag B737

The Boeing 737 is a short-to-medium-range twinjet narrow-body airliner. Originally developed as a shorter, lower-cost twin-engined airliner derived from Boeing’s 707 and 727, the 737 has developed into a family of ten passenger models with a capacity of 85 to 215 passengers. The 737 is Boeing’s only narrow-body airliner in production, with the -700, -800, and -900ER variants currently being built. A re-engined and redesigned version, the 737 MAX, is set to debut in 2017.

The Boeing B737 made its first flight in April 1967 and entered airline service in February 1968 at Lufthansa.
As of 2006 there were 1,250 Boeing 737s airborne at any given time on average, with two departing or landing somewhere every five seconds.
