Nozzle blown out
description
Motor exploded immediately after ignition. Rocket did not lift off. Examination of the motor afterwards showed the nozzle completely gone. It was apparently blown out the back end of the motor at the time of the explosion. There was nothing left in the motor case: no nozzle, no propellant, no clay cap.
