The fastest commercial airliner still in service today is the 50-year-old Boeing 747, which can reach speeds of up to Mach 0.92, or 706 mph at sea level.
Meanwhile, the Boeing 787 Dreamliner is the world’s fastest twin-engine widebody jet and can journey at Mach 0.90, or 690 mph.
Some of the fastest aircraft in the sky, however, are purpose-built private jets.
And, they’re getting even faster as manufacturers battle to attract deep-pocket customers who prefer the privacy and convenience of private flying over commercial airlines.
Here are some of the fastest private jets in the world — with one actually exceeding Mach 1 during a test flight.
Dassault Falcon 7X/8X: Mach 0.90 (690 mph)
The tri-engine Dassault Falcon 8X is the successor to the Falcon 7X with a longer range, better engines, and new avionics. Both can reach up to Mach 0.90, or about 690 mph at sea level.
Pop sensation Taylor Swift famously owns a Dassault 7X, which has followed her along her colossal Eras Tour this year.
