The Boeing 737 is a short-to-medium-range narrow-body jet airliner developed by Boeing Commercial Airplanes. First flying in 1967, it has grown into a broad family spanning multiple generations — the Original (-100/-200), Classic (-300/-400/-500), Next Generation (-600/-700/-800/-900), and MAX series — making it the most produced commercial jetliner in aviation history. Each generation brought improved fuel efficiency, updated avionics, and extended range capabilities, allowing the 737 to serve routes from domestic short hops to transcontinental flights. The aircraft is operated by hundreds of airlines on every continent and has become the backbone of many carriers' fleets worldwide. The 737 MAX series, introduced in the 2010s, featured CFM LEAP-1B engines and significant fuel savings but was grounded globally from March 2019 to late 2020 following two fatal crashes linked to the MCAS flight control software. The MAX returned to service after extensive regulatory review and software modifications.

Encyclopaedia

The Boeing 737 is an American narrow-body aircraft produced by Boeing at its factories in Washington state. Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines. Envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered service in February 1968 with Lufthansa. The lengthened 737-200 entered service in April 1968, and evolved through four generations, offering several variants for 85 to 215 passengers.
