Bombardier announced a high-performance Bombardier Learjet 75 aircraft has set a world speed record in its class, flying round trip between New York and Los Angeles.

The flight, piloted by two members of Bombardier’s flight operations demonstration team, was staged to mark the 50th anniversary of Clay Lacy’s 1965 record-setting transcontinental round-trip flight.

Bombardier said, to date, aircraft in the Learjet family have accumulated 111 world speed records.

The attempt, which took place on September 10, 2015, and followed the original 4,946-mile route but in reverse, beat Lacy’s flying time by 17 minutes. Lacy’s original flight in a Learjet 23 aircraft made aviation history, marking the first time a business jet made a round-trip flight across the U.S. between sunrise and sunset on the same day.

The Learjet 75 aircraft departed Westchester County Airport in White Plains, NY at 8 a.m. EDT, flying at a maximum cruising speed of M 0.81. The aircraft touched down at Dwight D. Eisenhower Airport in Wichita, KS for refueling on both legs of the flight and also at Van Nuys Airport in Los Angeles where Clay Lacy, flanked by the original Learjet 23 aircraft, was on hand to offer encouragement. The pilots returned to Westchester County Airport at 8:26 p.m. with more than adequate fuel reserves and a new record under their belts.
