A Milestone for our experimental supersonic airline!!

Supersonic airlines are aircraft that can travel at speeds greater than the speed of sound, typically defined as Mach 1, which is approximately 767 miles per hour (1,235 kilometers per hour) at sea level and room temperature. The most famous supersonic airliner was the Concorde, which operated from 1976 to 2003. In recent years, there have been efforts to develop new supersonic commercial aircraft with improved technology and efficiency, but as of my last knowledge update in September 2021, none had entered regular commercial service. Please check the latest developments for any updates on supersonic airliners.
