Sound Barrier


The sound barrier is the point at which an aircraft moves from subsonic to supersonic speed, causing a sonic boom. It is the sudden increase in aerodynamic drag and air resistance that occurs when an aircraft approaches the speed of sound. The sound barrier varies depending on factors such as altitude, temperature, and humidity. Breaking the sound barrier was a significant achievement in aviation history, and it opened up new possibilities for high-speed flight. Today, many military aircraft and some commercial planes are designed to fly at supersonic speeds.
