I emailed Estes a detailed summation as to what had happened. Included several photo's of the engine nozzle being cracked and partially blown out, the burnt rocket and of course a photo of the blown apart pieces on the launchpad.
After 3 days, got no response, so I called today. They are sending me replacement pack of engines, and a new rocket ! Also reminded me to store all engines in closed moisture resistant containers out of extreme temperatures. I mentioned I had been storing them in metal US Army Ammo cans and she said that would be perfect, and store in a cool dry place.
She had no info as to a production problem or quality problem, so I guess just a bad engine.
