Feb 9, 1963 | 1st test flight of Boeing 727 jet
One of the world's classic airliners, the Boeing 727 was built to carry on the successful legacy of its forerunner, the 707. With a low-altitude, high-speed cruising capability, it provided economic jet travel on short- and medium-range routes and was able to serve smaller airports. Its production run extended from 1963 to 1984, producing a total of 1,832 units that were flown by more than 100 different airlines. It was the world's best-selling passenger jet in its time, until it was surpassed by the next generation of airliners, the Boeing 737 and Airbus A320.
The 727 is instantly recognizable by its tail-mounted, tri-jet configuration. The key to its short runway performance was its innovative high-lift system of triple-slotted trailing edge flaps, outboard leading edge slats, and inboard leading-edge Krueger flaps.
