Burning propellant ejected
Three CATOs out of a package of four motors. Motors were purchased direct from Estes Industries on 2/2/22. Total order was twelve packages of four motors totaling forty eight motors. I still have forty five motors remaining, all from this same lot. Motors have bee stored under ideal conditions and have not been subjected to any extremes of temperature, hot or cold, while in my possession. Note the extreme blackening of the forward motor casing ends. The rear of the rocket was completely burned up by the ejected material.
There was no delay charge or tracking smoke. Models achieved ~50 ft of altitude whereupon all the remaining material from the engine was ejected forward in a fireball through the models.
