United Airlines 737-300 over Kent, Southern England

The Boeing 737 is a short to medium range, single aisle, narrow body jet airliner. Originally developed as a shorter, lower cost twin engine airliner derived from Boeing's 707 and 727, the 737 has nine variants, from the early -100 to the most recent and largest, the -900. Currently series -600 through -900 are being produced.

First envisioned in 1964, the 737 entered service in 1968. Forty years later it has become the most ordered and produced commercial passenger jet in the world. It is Boeing's last surviving narrow-body airliner, sometimes serving markets previously filled by 707, 727, 757, DC-9 and MD-80/90 airliners. Continuously manufactured by Boeing since 1967 with 9,295 aircraft delivered and 4,280 orders yet to be fulfilled as of November 2016, there are over 1,250 737s airborne at any given time. On average, a 737 departs or lands somewhere every five seconds.
