motor blew on ignition. Rocket never made it off the rail. Motor case sheared off at the end of the threads of the aft closure. Aft closure ejected so violently that it was badly damaged when it hit the blast deflector. Aeropack retainer was also destroyed. Fuel grain and all other components ejected. Fuel grain did not continue to burn. Forward closure and rest of case blew up the airframe and destroyed the bulkhead and ebay.
