description
Aft closure blew out upon ignition. The aft closure exited the rocket attached to the motor retainer, while the casing, fuel grain, and delay were ejected and scattered in an approximately 20 foot radius. The motor had been properly assembled per the instructions, and both forward and aft closures were threaded by hand into the casing. The closures were not cross threaded, and were flush with the casing. The forward closure was still attached to the casing, and the ejection charge was still in the well.
