SpeedThe Concorde cruises at Mach 2, or twice the speed of sound*. That means you can get to places in a Concorde faster than in a regular airplane. In fact, you can "arrive before you leave!" How? Well, it's a matter of timing. For example, if you flew from London to New York, it would take you 3.5 hours. You could leave London at 5 PM and arrive in New York at 3:30 PM—1.5 hours before time of take-off! Why? Because you crossed 5 time zones (setting the clock back 5 hours) in just 3.5 hours.Concorde Speed Facts
