United Airlines Boeing B727-100 Collection

The Boeing B727-100 is a version of the Boeing 727, which was designed in June 1959. A major innovation of the 727 was the choice of a rear-engined layout, with two Pratt & Whitney JT8D turbofan engines mounted on the sides of the rear fuselage and a third at the base of the T-tail assembly. The 727 had an identical upper fuselage to the 707 and 720 series, with many parts interchangeable. The 727-100 version of the 727 provided standard transport for up to 131 passengers.
