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