The U.S. government considers anyone who travels 264,000 feet above the ground as an astronaut. So, this rocket did pretty good. The video is more telling, quite the backyard project:

Led by Derek Deville, the rocketeers launched their custom-built 26 ft. (8 meter) Qu8k (pronounced “Quake”) rocket on September 30, 2011 from the Black Rock Desert in Nevada. It reached an altitude of 121,000 feet (36,880 meter) in 92 seconds, at speeds of 2,185 mph (3,516 km/h).
