Just to clarify: I am explicitly not referring to the Bell X-1, or any other early experimental supersonic aircraft that were rocket powered. I'm curious as to the first supersonic aircraft powered by an air breathing jet engine, as well as (if possible) the technological innovations needed to transition from rocket powered to air breathing supersonic flight.
