The 737 is the world's most successful jet airliner family. The 737 was conceived as a short range small capacity airliner usually seating 100 passengers depending on seating configurations. The 737 is primarily used in passenger operations, however, various all cargo 737s are still available in the market today. The aircraft's success is due to its sturdy structure, unparalleled stability, fuel economy, system simplicity, low costs in maintenance/ ground handling, and the affection of both pilots and passengers worldwide.
The B737 twin-jet includes two underwing mounted JT8D turbofans and 60% structural and systems commonality with the 727, including the same fuselage cross section. Even today, 40 years after its development, the 737 continues to be the most economic jet airliner in the market today.
