The Boeing 727 is a narrow-body, three-engine commercial jetliner that was first introduced in 1963. Designed for short to medium-haul flights, it became popular for its versatility and ability to operate from shorter runways. The aircraft can accommodate around 150 passengers and is known for its distinctive T-tail design. The Boeing 727 was produced until 1984, with over 1,800 units built, making it one of the most successful jetliners of its time. It played a significant role in the expansion of air travel during the late 20th century and is still used in some cargo operations today.
