Supersonic.
sonic boom as the planes speed exceeds the sound barrier.
The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
Those are ultra sonic planes. There is a sonic boom if it is traveling with sound speed.
The first American pilot to exceed the speed of sound in an airplane was Chuck Yeager.
The speed of sound is proportionally less and vary s according to altitude. when ever air craft exceeds the speed of sound it is defined as i mach. those air crafts capable of crossing sound speed is called supersonic.
It is going faster than the speed of sound.
Yes.
Crack a whip, its tip exceeds the speed of sound.
No. The sonic boom will be created by any speed that is greater than the speed of sound.
A sonic boom occurs during the entire time the plane exceeds the speed of sound
That's not true.
Only if it's traveling at less than the speed of sound
