Why does a supersonic plane disappear when you hear its sound?
When a supersonic plane goes faster than the speed of sound, it creates a shockwave causing a sonic boom. The sound you hear after the plane has passed is the shockwave catching up to the aircraft. This can create the illusion that the plane has disappeared along with the sound.
Would a pilot in a plane breaking the sound barrier hear a sonic boom?
No, the pilot inside the plane would not typically hear the sonic boom generated by their aircraft when breaking the sound barrier. The shockwaves are behind the plane, so they wouldn't be able to hear it. They may feel some vibration or turbulence, but not the sonic boom itself.
If you were traveling in a plane at a supersonic speed would you hear the engines?
YesWhen a plane goes through the sound barrier, it produces a wake like a boat going through water. The wake(or waves) propagate out from behind the plane in a cone. Any observer outside this cone does not hear the plane until the shock cone reaches him.If you are a passenger on the plane, then you are traveling the same speed so the sound waves will reach you easily.It is like the illustration of a Fly inside a plane. The Fly can still fly from the back of the plane to the front but he is not going supersonic. He would appear to be going supersonic to someone on the ground.ALso, read the observations of the Astronauts. Their space shuttle reaches Mach 2 or 3 before engine separation and I'm sure they will describe the change in sound.ALTERNATE QUESTION:Do you hear your rockets if you are in Space? There is no atmosphere in space so sound can not travel. However, there is atmosphere inside the rocket so they do hear the vibration.
Noise of a plane approaching at a speed of 1000mph is not heard do you know why?
The speed of sound is approximately 767 mph, so if the plane is moving faster than the speed of sound (supersonic), the noise it generates will not reach the observer until after the plane has passed. This phenomenon is known as a sonic boom.
Who was the first person to hear sound?
It is difficult to determine exactly who was the first person to hear sound, as sound has been present since the beginning of time. However, the first person to scientifically study sound and its perception was likely Pythagoras, an ancient Greek philosopher and mathematician.
Can you hear a plane which is 1000 meters high?
Yes, you can hear a plane witch is 1000 meters high.
Can you hear a plane at 5000 feet?
yes, you can hear planes at 35000 feet.
What happens when the plane goes faster the speed of sound?
You would hear the sound after the plane has passed.

If you see lightning first and hear thurnder later what does that mean?
It just means that light travels faster than sound does :)
What if you dont hear the baby hearts beat?
it depends how far along in the pregnancy. in the first month it can sometimes be to early to hear, if it is later in the pregnancy that typically means the baby has passed away.

Why dont fighter jets make noise?
They do make noise. If they fly very high, then you can't hear them.
If you hear a jet flying where should you look to locate the plane?
sonic boom
Can you see a plane going Mach 2.4?
Yes - but it will be travelling fast ! You will hear the sound of the engines a few seconds after the plane passes overhead.
If you are driving and you hear a siren coming what should you do?
move to the side and let the police, ambulance, or fire fighter car go through
What does the brain register first- visual or audio information?
I think your brain processes visual information first because you naturally see things before you hear them. Like when you see a person hit a pitch, you see it but and instant later you hear the "crack". That has to do with light traveling faster than sound.
