History of Boeing 727

Source: Wikipedia

The Boeing 727 is an American narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavy 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964.

The only trijet aircraft to be produced by Boeing, the 727 is powered by Pratt & Whitney JT8D low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct. It shares its six-abreast upper fuselage cross-section and cockpit with the 707. The 133 ft (40.5 m) long 727-100 typically carries 106 passengers in two classes over 2,250 nmi (4,170 km), or 129 in a single class. Launched in 1965, the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that December. The 20 ft (6.1 m) longer variant typically carries 134 passengers in two classes over 2,550 nmi (4,720 km), or 155 in a single class. Besides the airliner accommodation, a freighter and a Quick Change convertible version were offered.

The first 727-100 (N7001U) flew on February 9, 1963. FAA type approval was awarded on December 24 of that year, with initial delivery to United Airlines on October 29, 1963, to allow pilot training to commence. The first 727 passenger service was flown by Eastern Air Lines on February 1, 1964, between Miami, Washington, DC, and Philadelphia.

A total of 571 Boeing 727-00/100 series aircraft were delivered (407 -100s, 53 -100Cs, and 111 -100QCs), the last in October 1972. One 727-100 was retained by Boeing, bringing total production to 572.

The -100 designation was assigned retroactively to distinguish the original short-body version. Actual aircraft followed a "727-00" pattern. Aircraft were delivered for United Airlines as 727-22, for American Airlines as 727-23, and so on (not -122, -123, etc.) and these designations were retained even after the advent of the 727-200.
