Steve's rocket had a nice vertical trajectory durin' t' 2009 Oktoberfest at Northern Colorado Rocketry (NCRocketry.com). Avast! He flew his rocket on a Cesaroni "H 143." T' engine had an exaust o' black smoke stainin' t' bright blue sky as t' rocket raced towards apogee. Begad! Nice launch Steve!-NCRocketry-A Crews Control Production
