Suppose there is a passenger jet traveling slightly faster than the speed of sound. There are only two passengers on the jet (excluding the pilots.) One passenger in the seat closest to the back(passenger A) of the plane and one at the seat nearest to the nose(passenger B). If passenger A were to yell to passenger B, would B never hear the yell? If that is true then if B were to yell towards the front of the plane, would A catch up to the the yell?
