The forward bulkhead held allowing deployment even though the rocket was split at fin due to CATO. Failure point: Side of motor case just above and on aft closure. Burn through/failure. About 2 seconds of video from ground is missing due to my stunned reaction when failure began. Unfortunately video is not UHD. Rocket was burned due to 10 foot diameter brush fire initiated at landing. Thank you Jonathan Holloway for extinguishing fire. Electronics, bay, nose, and chutes were out of the burn circle and are unharmed.
