Comments
Rocket was just starting up launch rail when it blew the nose cone and parachute out of rocket. The motor immediately quit burning. The forward end of the motor with the delay grain and ejection charge unburned was up inside the rocket body. The case with the fuel grains was cracked from the edge of the nozzle end cap all the was to where the delay cap separated. I had difficulty removing the case from the rocket because it had swelled as well as cracked.
