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