When was the first supersonic flight?
The first plane to fly at a supersonic speed, which is a speed greater than the velocity of sound, was a Bell X-1 rocket-powered research plane that flew October 14, 1947. Many military aircraft were then built for supersonic flights. The first commercial airplane designed to carry passengers at supersonic speeds was the Concorde, built by the French and British governments. It entered regular service on January 21, 1976, with cruising speeds of 1,354 miles per hour.
