Boeing 737 Family
The most delivered commercial jet airliner in civil aviation history
Aviation Heritage & Operational Role
The Boeing 737 is the backbone of global short and medium-haul air travel. Originally conceived in 1964 as a regional feeder for the larger 707 and 727, the twin-engine jet has evolved across four distinct generations: Original (-100/-200), Classic (-300/-400/-500), Next Generation (-600/-700/-800/-900ER), and the modern MAX series. With more than 11,000 airframes delivered, a 737 takes off somewhere in the world every few seconds.
