The longer-range Model 36 has a shortened passenger area to provide more space in the aft fuselage for fuel tanks.[2] As a result of the increased power and reduced noise of the new engine, Learjet further improved the design, and instead of being simply a variant of the 25, it became its own model, the 35.[4] In 1976 American professional golfer Arnold Palmer used a Learjet 36 to establish a new round-the-world class record of 22,894 miles (36990 km) completed in 57 hours 25 minutes 42 seconds.[4] During the Cold War, the Finnish Air Force used the Learjet 35/36 as a shorter range AWACS aircraft, for monitoring Soviet bombers and fighter jets coming over the Baltic Sea and over the Arctic.[6] On February 12, 1996, a Learjet 35A, N10BD,[8] owned by Cable Television Founder Bill Daniels and piloted by Mark E. Calkins, Charles Conrad, Jr., Paul Thayer, and D. Miller completed an around-the-world flight in a record 49 hrs, 21 min, and 8 sec.[4] As a private jet the Learjet 35 was popular because of its good range (it can fly 2,056 miles nonstop), takeoff and landing performance (its Honeywell engines provide 3,500 pounds of thrust and can land on short runways at regional airports), fast cruise capabilities (it can cruise at speeds as high as 451 knots true airspeed (KTAS), or 424 KTAS with four passengers), good handling characteristics, a low fuel burn, and comfortable cabins.[12] A 2018 survey by Corporate Jet Investor found 14.9% of Americans recognized the Learjet brand compared with 12.5% for Boeing.
