Learjet 31
The Learjet 31 updated the long-running Learjet 35's fuselage with a new, more efficient 'Delta Fin' ventral fin and winglets borrowed from the larger Learjet 55, improving both stability and fuel efficiency. It kept the same compact, fast-climbing character that made earlier Learjets famous, prized by charter and corporate operators who valued speed over cabin space. Its relatively small cabin, cramped compared with newer light jets, reflected Learjet's original 1960s design priorities of speed and altitude above passenger comfort. It remained a common sight in air-taxi and corporate fleets through the 1990s and 2000s.
