BOOM!  barely cleared t' rod and t' motor CATO’d. Well, blow me down! Motor mount blew out t' back, me hearties, nose cone, chute and recovery harness blew out t' front. Ya scallywag!  T' body continued up for 100 feet or so and then raced over and came in ballistic, me hearties, crumplin' t' body tube and snappin' off one fin. Blimey!  This was t' first motor out o' a new pack so kind o' unexpected.
