This rocket flew out of control during the premier Oktoberfest launch in Northern Colorado. This was part of the Northern Colorado Rocketry club (NCRocketry.com). The rocket was an oversized "Mean Machine" that flew HP (High Power) on a "K" class motor. The rocket probably lost control because it lost a fin/s at the first 300 ft. of the flight. The rocket then lost stability and flew out of control .
