Screamin' Mimi on a D12-5. Shock cord attachment (kevlar) broke durin' descent, ya bilge rat, shortly after successful parachute deployment. Avast! Probably should have used a D12-3; probably t' rocket be headin' down too fast when t' charge blew. No damage t' t' main unit surprisingly, and t' nosecone landed within a few hundred feed o' t' pad. Begad! She will fly again soon. Well, blow me down! Main disappointment was: No screaming!
