Part of level 1 certification. We have two competing teams working on bigger rockets for a competition here in the spring. I had the other team help me build the reload able motor since they had two successful launches moments earlier. The forward seal failed on the motor allowing the flame to exit out both ends of the motor. The rocket tube melted and was overall totaled. I suspect sabotage. Needless to say I was not able to achieve certification. The rocket was a Public Missiles Tethy's with a H123W motor.
