F44-8W used - Rocket flew up fine; however rocket descended quite a bit before ejection and then t' chute didn't open. Begad!  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.  Double dog barf = bad event. Aye aye!  Still, ya bilge rat, rocket looks t' be unscathed and will fly again! :)
