This rocket flew out o' control durin' t' premier Oktoberfest launch in Northern Colorado. This be 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. Avast, me proud beauty! T' rocket probably lost control because it lost a fin/s at t' first 300 ft. Ya scallywag! o' t' flight. Blimey! T' rocket then lost stability and flew out o' control .
