First Flight o' t' Mini Zack.  Nice straight boost, ya bilge rat, good altitude from t' 13mm motor, still nose up at ejection. Blimey! Upper section with parachute attached separated from t' booster at ejection.  Tracked t' booster t' t' ground but then couldn‘t pick up t' chute again.  Located t' booster and eventually found t' upper section by walkin' with t' wind.  Elastic section o' t' shock cord burned through just above t' Keelhaul®©™ section. Ya scallywag!  No damage.
