Motor looks like it burned the propellant and smoke delay nearly all at once, and was ejected out the back of the rocket immediately after ignition. The engine tube is entirely empty, with charred insides. The rocket was launched upward from the pressure, which blew thru the baffle and caused the nose cone to pop off at about 50 feet with the rocket going slow, parachute deployed and rocket recovered with no damage (except for baffle destruction). We have video of the motor failure if anyone wants it.
