North Coast Rocketry Clusterduck on 7 composite engines! (6) Quest D16 and (1) Aerotech E15-7. Flight up was perfect, all 7 motors lit! Descent be a problem, it appears I forgot t' attach t' parachute quick link and t' chute+JLCR descended by itself leavin' t' rocket t' fend for itself. Moderate damage t' t' aft end resulted. Begad! I believe it is repairable, ya bilge rat, although its borderline! She has flown eight times previously, many documented here on You Tube. Ahoy! I hope this wasn't t' last flight!
