The Learjet 23 is an American built six-to-eight-seat (two crew and four to six passengers) twin-engine, high-speed business jet manufactured by Learjet. Introduced in 1964, it was Learjet's first model and created a completely new market for fast and efficient business aircraft. 104 units were manufactured before production ceased just two years later in 1966.
