description
Not entirely sure of the exact failure mode, but the motor only partially ignited, with the rocket flying ~100 ft in the air before lawn darting. 5/7 unburned propellant grains were found in the vicinity, along with pieces of a 6th. The rear thrust ring was broken off of the rocket, but it is unclear if that was from the launch or from the impact.
Comments
Motor did not completely start burning but "chuffed" for <1 second before stopping completely, and never ignited fully.
