Boeing 737 Original

The Boeing 737 Original series, introduced in 1967, marked the beginning of what would become the world’s best‑selling commercial jet. Developed as a short‑range, twin‑engine airliner to compete with the Douglas DC‑9, the 737‑100 and larger 737‑200 variants featured a low‑wing design, flap‑less wings and Pratt & Whitney JT8D low‑bypass turbofan engines that offered improved fuel efficiency and reduced noise compared to earlier jets. Its simple, robust structure and commonality with the popular 727 allowed airlines to share pilot training and maintenance facilities, lowering operating costs. First deliveries went to Lufthansa and United Airlines, and the model quickly proved popular for regional and domestic routes because of its short take‑off and landing capability on modest runways. The 737 Original set the foundation for the “Classic,” “Next‑Generation,” and “MAX” families, establishing design philosophies—such as the twin‑engine, narrow‑body layout and cockpit commonality—that remain central to modern aviation. Over 1,000 Original series aircraft were built before production shifted in the early 1980s, leaving a legacy of reliability that helped Boeing dominate the single‑aisle market for decades. Its enduring influence is evident in the continued popularity of the 737 platform, which today serves airlines worldwide across all market segments.
