Nose cone separation at ejection, me bucko, but everythin' came down fine. Aye aye! Whistles were very faint and audible only near t' end after motors finished thrusting. Landed near by (in 2 parts o' course).   Rubber Estes shock cord broke right where it is knotted at t' nosecone - could be due t' me usin' CA on t' knot or possibly extra strong ejection charge.
