BAC One-Eleven

The BAC One-Eleven is a short-haul jet airliner built by the British Aircraft Corporation, originally conceived by Hunting Aircraft as an 80-seat design before Hunting merged into BAC in 1960 and the first order arrived from British United Airways in 1961. The prototype first flew on 20 August 1963 and the aircraft entered service on 22 January 1965, competing directly with the Douglas DC-9 and Boeing 737 on the strength of aft-mounted Rolls-Royce Spey turbofan engines, a layout it shared with the Sud Aviation Caravelle; a stretched 500-series variant introduced in 1967 carried up to 119 passengers. British and later Romanian production totaled 244 aircraft between 1963 and 1989, and the last flyable example, used as an F-35 sensor testbed by Northrop Grumman, was retired in 2019.
