I had this discussion with my dad about a question he had asked. Basically he said:
If a plane flies faster than the speed of sound, will he be able to overtake his own sound and hear itself?
(let's leave behind the fact that he can run out of fuel or that the sound finishes before he hears it)
I disagreed because it seemed illogical to me, but we never actually found hard evidence to determine if the statement is true or false.
Can a plane actually do this?
