|Interpretation||First flown in February 1963, the Boeing 727-100 became essential to commercial short and medium-range air travel. It was one of the best-selling jetliners in commercial aviation history and is flown throughout the world by over 100 different airlines. The 727 was built to accommodate short runways. Its three tail-mounted engines proved to be very efficient. The 727's other main selling point was its unique wing flaps arrangement. Opening the flaps increased the wing area by 25 percent. Production ended in 1984 after 1,832 727 turbojets had been manufactured and sold. The Museum's 727, a Boeing model B 727-100, was among the first group of 727s purchased by United Airlines and has been repainted in United's 1964 colors. It was delivered to United Airlines on May 29, 1964, and used primarily on domestic flights. It was retired from the United fleet in the autumn of 1992 after 28 years of service in which it carried over three million passengers and logged some 28 million miles. The Boeing 727-100 became part of the Museum of Science and Industry's collection in 1993. The Model B 727-100 is also the centerpiece of the 'Take Flight' multimedia program that shows how various parts of an airplane operate. Visitors are encouraged to walk through the aircraft and observe sections of the plane in operation.|
