F/A-18C Hornet beaking the sound barrier-
At sea level a plane must exceed 741mph to break the sound barrier, or the speed at which sound travels. The change in pressure as the plane outruns all of the pressure and sound waves in front of it are heard on the ground as an explosion or sonic boom. The pressure change condenses the water in the air as the jet passes these waves. Altitude, wind speed, humidity, the shape and trajectory of the plane - all of these affect the breaking of this barrier. The slightest drag or atmospheric pull on the plane shatters the vapor oval like fireworks as the plane passes through.

You see this vapor flicker around the plane that gets bigger and bigger. You get this loud boom, and it's instantaneous. The vapor cloud is there, and then it's not there and the plane is kicking ass at that point!
