Captain Jack McClure is famous in drag-racing circles for driving a go-kart powered by a rocket. That's pretty obvious from the title of the documentary about him, "Captain Jack and His Rocket Powered Go-Kart." It only takes a few minutes of watching Captain Jack to see why filmmakers Krystal Alexandria and Daniel Hagler chose to share his story. Krystal Clear MediaMcClure's first rocket kart used a pair of Turbonique turbine engines. That was it until 2011, when McClure found his old kart and decided to run it one last time.
