40 Photos of Airplanes Breaking the Sound Barrier » TwistedSifter

The lag you hear is because light travels faster than sound, hence, you see it before you hear it. If you listen closely you will notice the same thing with little propeller-driven planes if they're far enough away, they fly little more than mph if that.

The speed of sound, jet planes breaking the sound barrier key the "sound barrier" is about mph at sea level depending on air density. Relatively few aircraft can reach that speed and must be specially designed to do so, for example notice how different a fighter jet is from a commercial airliner.

The boom or "sonic boom" is complicated to explain but it is basically caused by the air pressure around the Jet Planes Breaking The Sound Barrier Design plane suddenly equalizing as the plane catches up to it's own sound waves. The puff of air you see known as a vapor cloud is caused by the low llanes, high-speed air pulling the moisture out of the sojnd air making it visible in the low pressure pockets around the plane. You don't have to be going super-sonic for this though, all you need is speed combined with moist air.

You can even see it coming off of jet planes breaking the sound barrier key airliner landing on a cloudy day at around mph. Most of the time it is visible when a plane breaks the sound barrier because the plane is going so fast it is basically wringing the water out of the air.

However, I did see an F fighter jet go super-sonic in the Persian Gulf without any vapor breking all because the air was so dry. The atmosphere is a complicated place isn't it? Not all planes are capable of breaking the sound barrier. Pretty much all fighter aircraft can break the sound barrier, and the B-1 Spirit bomber can break the sound barrier, but other planes like cargo planes and commercial airliners are not designed to go faster than the speed of sound.

Supersonic jets are only allowed to break the sound barrier over large bodies of water except in plames of extreme emergency. Only the planes that go over feet per second the approximate speed of sound break the jet planes breaking the sound barrier key barrier. Lpanes so called lag you see is because light travels faster than sound. So you see jet planes breaking the sound barrier key plane, but hear it after it passes that point.

Jun 13,  · NORFOLK, Virginia (June 2, )- An F/AC Hornet attached to the “Raging Bulls” of Strike Fighter Squadron (VFA) 37 punches through a cloud of water vapor while breaking the sound barrier during an air power demonstration on board the Nimitz-class aircraft carrier USS Harry S. Truman (CVN 75).
