BAC One-Eleven
Before the airplane was called the BAC 1-11, it was called the Hunting 107 before Hunting Aircraft merged with British Aircraft corporation. It entered service in 1965, a while before it's competitors. Despite it being a British aircraft, half of the original orders were American. During the 1980s noise restrictions were passed, and most airlines wanted to hush-kit the aircraft instead of putting the aircraft out of service. They did this because at least half of the 1-11s still in service were fairly new; only 5-10 years old. During the early 1990s, more noise restrictions were passed, and this time, the planes were approaching retirement age anyway, so the BAC 1-11 saw most airlines retiring them in the 90s. The last ones in service were testbeds for the Lockheed Martin F-35 Lightning II, and those were retired in 2019.
