About the Boeing B737

The Boeing 737 series began development in 1967 and has since grown to include nine passenger models. With timely upgrades, Boeing moved firstly from the original B737-100 to a lengthened model, B737-200. The launch of the B737-300, B737-400 and B737-500 followed. This series later became known as the B737 Classic, prompted by the launch of the B737NG (Next-Generation) series, which incorporates the B737-600, B737-700, B737-800, and B737-900. Where the classic series was fitted with the optional Electronic Flight Information System (EFIS) rather than analog dials, terminology blurred, and as a result, B737-3/4/500 fitted with EFIS, are often abbreviated to B737 EFIS. It is estimated that there are an average of 1,250 airborne B737 aircraft at any time, with two either taking off or landing every five seconds. Due to the B737's successful history and continued plans for development, the B737 is assured a great future!
