Can the 747 break the sound barrier?
As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.
Can humans fly faster than sound?
Supersonic humans Felix Baumgartner, a skydiver from Austria, achieved faster-than-sound speed during his famous supersonic freefall in 2012. If you are thinking about trying it our yourself, keep in mind that you will need an air balloon and a pressure suit.
Has a car broken the sound barrier?
Thrust SSC holds the world land speed record, set on 15 October 1997, and driven by Andy Green, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier. Both Thrust SSC and Thrust2 are displayed at the Coventry Transport Museum in Coventry, England.
Can a plane fly faster than the speed of sound?
As such, its airspeed remains subsonic, even though, at first glance, its ground speed appears supersonic. Ultimately, an aircraft flies by airspeed rather than ground speed, so the crucial metric is its speed in relation to the air surrounding it.
Which is faster the speed of sound or Mach 1?
The T-38C, a supersonic US Air Force training jet that NASA imaged, traveled at a top speed of Mach 1.09 during the tests. (Mach 1 is the speed of sound, which is about 768 mph at sea level.) But the tricky maneuvering was worth it for these gorgeous images, showing the shock wave of the T-38 flying over the Mojave Desert:
What happens when an aircraft travels at supersonic speeds?
Supersonic speeds. When an aircraft travels at supersonic speeds or is moving faster than sound, it leaves the sound waves it makes behind it. These waves fan out and cause a sonic boom. Summary. An object moving through air not only must push some of the air out of the way, but it also creates sound waves.
Which is faster Concorde or the speed of sound?
The speed of sound (at 20 °C/68 °F in dry air) is equal to around 343 meters per second. This adds up to a rapid 1,235 km/h, 767 mph, or 667 knots. Concorde was capable of cruising at more than twice this speed.

Why does a plane have a sonic boom?
The sonic boom is not just a one-time result of breaking the sound barrier. Because the plane is creating shock waves the entire time it flies at supersonic speeds, sonic booms can be heard the entire time as well.
