Learjet 23
The Learjet 23 brought fighter-inspired proportions and high cruising speed to the early business-jet market. Its compact cabin, pointed nose and tip tanks became the visual template for the first Learjet generation, aimed at executives seeking direct travel in a small dedicated jet.

Overview
Program history
Bill Lear began the project around the aerodynamic ideas of the Swiss P-16 fighter before moving production to Wichita. The resulting Learjet 23 first flew in October 1963 and helped establish a market for small, fast corporate jets. Subsequent Learjet 24 and 25 aircraft developed the formula with revised certification, capacity and operating characteristics.
