Cutaway artwork of the Douglas D-558-I Skystreak, a transonic research plane designed and built in the mid 1940’s for the US Navy. Like the contemporary Bell X-1 rocket plane, it had straight wings; but unlike the X-1, it had a turbojet engine and could take off under its own power. It could only get supersonic in a dive. Douglas followed the D-558-I with the D-558-II Skyrocket, a very different and much more advanced aircraft that could fly much faster.
