oh I see! yeah the v2 was faster than the speed of sound but the v1 wasnt and so the engine had to shutdown when it was almost ready for impact. So with the v2 u couldnt hear it anyway cus it was 3 times the speed of sound until u were blown up!
Did u know that the guy called braun who worked on the rockets was responsible for getting the americans to the moon.
Thanks oddball
