This alternate version features the SuperDraco engine testing without music.
Original version is available here:
SpaceX successfully test fires SuperDraco, a powerful new engine that will play a critical role in efforts to change the future of human spaceflight. These engines will power a revolutionary launch escape system that will make Dragon the safest spacecraft in history and enable it to land propulsively on Earth or another planet with pinpoint accuracy. In a series of tests conducted at SpaceX’s Rocket Development Facility in McGregor, Texas, the SuperDraco sustained full duration, full thrust firing as well as a series of deep throttling demonstrations.
