On the limit of aircraft and spacecraft, the X-15 reached Mach 6.72 and an height of 107960 m. The X-15 was designed to resist the heat and friction of atmospheric reentry. It was powered by rocket engines. The X-15A-2 version could carry two large external fuel tanks. Three X-15s were built, one was lost in a fatal accident.
