"Launch of 3 stage rocket model, on-board camera slow motion video, rocket motors ignition sequence, detail of stage separation from additional on-board camera attached to 2nd stage. Slow motion video from external cameras. Flight safety control by on-board electro-mechanical gyro-vertical, accelerometer and electronics."
Very clear separation of the SRBs under parachutes and no rolling during boost. Definately worth watching!
