Learjet is a Canadian owned, American aerospace manufacturer of business jets for civilian and military use based in Wichita, Kansas. Founded in the late 1950s by William Powell Lear as Swiss American Aviation Corporation, it has been a subsidiary of Canadian Bombardier Aerospace since 1990, which markets it as the “Bombardier Learjet Family”.

Learjet was one of the first companies to manufacture a private, luxury aircraft. Lear’s preliminary design was based upon an experimental American military aircraft known as the Marvel, substituting fuselage-mounted turbojet engines for ducted fan turboshaft engines. However, that preliminary design was abandoned and the final Learjet design was instead adapted from an abortive 1950s Swiss ground-attack fighter aircraft, the FFA P-16.

The Learjet 60 is a mid-size cabin, medium-range business jet aircraft manufactured by Bombardier Aerospace in Wichita, Kansas. Powered by two Pratt & Whitney Canada PW305A engines, it has a range (with 4 passengers and 2 crew) of 2,405 nautical miles (4,454 km) with NBAA 100 nmi (190 km) reserves, ISA.  is an improved version of the Learjet 55, with a longer fuselage and more powerful turbofan engines. It first flew on 10 October 1990 and received FAA certification in January 1993.

The Learjet 60 is notable for its time-to-climb performance, climbing to 41,000 feet (12,497 m) in 18.5 minutes at maximum weight. It also distinguished as the last legacy Learjet, using the wing that designer Bill Lear adapted from the Swiss military aircraft, the FFA P-16. Production of the Learjet 60 ended in 2007 after 314 aircraft had been built.
