The Rednecks enter a NASA contest with the hopes of launching a man-capable rocket 1 mile into the sky. The custom 20-foot-tall missile boasts two engines and about 3,000 pounds of thrust fueled by a mixture of ammonium perchlorate and aluminum. The goal: Once the rocket reaches 1 mile, explosive charges will shoot a parachute out and allow the capsule, and the test dummy, to float safely back to earth.
