What is the Sound Barrier?

sound barrier is broken by any vehicle exceeding the speed of sound: 660mph

Once thought to be an impossible speed, Chuck Yeager broke the sound barrie.r with the Bell X-1 rocket plant in 1947. As an object moves through the air, it pushes nearby air molecules causing a domino-effect on surrounding molecules. This causes a pressure wave that can be interpreted as ‘sound.’ As a plane approaches the speed of sound, its pressure waves stack up ahead of it to form a massive area of pressurized air that we call a shock wave.

These shock waves are heard as sonic booms.

Fast Fact: Felix Baumgartner is planning a skydive from 36,500m Рhe will fall so fast he will become the first person to break the sound barrier without mechanical help.
