Semroc Saturn 1B flight on a cluster o' 4 Estes E9 motors. 3 contiguous shroud lines, out o' 8 shroud lines, ya bilge rat, were ripped from t' parachute, so t' rocket came down pretty quick. No damage from descent. T' person "pushin' t' button" was 15' feet away from t' rocket (had relay controller problems).
