This rocket flew out o' control durin' t' premier Oktoberfest launch in Northern Colorado. This was part o' t' Northern Colorado Rocketry club (NCRocketry.com). Begad! T' rocket was an oversized "Mean Machine" that flew HP (High Power) on a "K" class motor. Begad! T' rocket probably lost control because it lost a fin/s at t' first 300 ft. Arrr! o' t' flight. Begad! T' rocket then lost stability and flew out o' control .
