Published on: April 2, 2013. NASA X-43A uses a drop launch method: it is lifted into the air by a larger aircraft and then dropped. The initial energy for propulsion is provided by a booster rocket, which is discarded when the aircraft reaches its target altitude and speed. From that moment, the X-43A is powered by its own jet engine.
