F44-8W used - Rocket flew up fine; however rocket descended quite a bit before ejection and then t' chute didn't open. Aye aye!  Rocket still recovered fine under parawad.  Post-flight inspection reveals I had packed in dog barf after it was already added from t' previous time and forgotten. Well, blow me down!  Double dog barf = bad event. Blimey!  Still, rocket looks t' be unscathed and will fly again! :)
