Jet planes often fly faster than sound.
Yes, many but mostly military. The Concorde passenger plane even flew above the speed of sound. Chuck Yeager is the first person credited with flying faster than the speed of sound in 1947. A few kinds of airplanes travel faster than sound, such as the Concorde SST and supersonic fighter jets.
With modern technology, there are many planes that can travel faster than the speed of sound, including many fighter planes and a few airliners.Any aircraft that flies faster than 1 Mach is faster than the speed of sound.Almost all modern day fighters travel at speeds in excess of the speed of sound. That includes the Russian MIGS from mig17 on, French Mirage, All US fighters.The planes which can fly at the speed of sound are SR-71, Mig-25, F-16, F-18, F-22, Sukhoi Su-47 and many others.
We call them ultra sonic planes. There is a sonic boom it is traveling when this speed.
An object moving at least five times the speed of sound is moving at hypersonic speed. Hypersonic speed is a speed greater than Mach 5. Aircrafts that can attain this speed are the X-15 rocket planes and Shuttle orbiter.
It is not true that the speed of sound cannot be broken. In fact almost all fighter jet planes fly faster than the speed of sound.Its the speed of LIGHT that cannot be broken.
Every airplane has its own speed limits. Most small and commercial planes fly below Mach (the speed of sound). Military fighters and some other planes, like Concorde, fly above Mach, or supersonically.
Bullets flies at the top speed of Mach 3 but almost Mach 4. There are some planes that can fly much faster than bullets but bullets used to fly faster than most planes(aircraft). Hypersonic aircraft can fly up to Mach 9. So yes, hypersonic aircraft can fly much faster than bullets. If these hypersonic planes can fly faster than bullets, they can fly alot faster than missiles. Missiles also flies around Mach 3 but hypersonic planes don't fly at that kind of speed. The top speed that hypersonic planes is nearly Mach 10(almost 10 times faster than the speed of sound).
Small planes fly at 100 to 200 mph. Airliners fly around 350 to 500 mph. Jet fighters fly faster.
Most passenger airplanes fly in the stratosphere. Planes like Cessna fly near the troposphere. It depends on the size and sound of the planes.
Only jet fighter planes break sound barrier now.
They are called Supersonic aircraft. Some aircraft can only do that. Some planes have reached even Hypersonic speeds.
Because breaking the sound barrier requires exceeding the speed of sound. The speed of sound is approximately 761 miles per hour at seal level at an the air temperature of 59 degrees Fahrenheit.
Ordinary jet engines are used on aircrafts. But some planes require turbojet engines. These planes fly at more than the speed of sound. There are other type of airplane types too.
High-speed fighter planes have aerofoil-shaped wings.
We can use ultrasonic planes. They can travel with that speed.
