Supersonic transport refers to aircraft that can travel faster than the speed of sound, which is approximately 767 miles per hour (1,235 kilometers per hour) at sea level. These planes are designed to reduce travel time significantly, allowing passengers to reach their destinations much quicker than conventional subsonic aircraft. The most famous example of supersonic transport is the Concorde, which operated from 1976 until 2003. Supersonic transport technology has advanced over the years, with new designs aiming to minimize noise and environmental impact. Current projects, such as those by Boom Supersonic, focus on creating more efficient and quieter supersonic jets, potentially making this mode of travel more accessible in the future.
