The subpanel approved the conclusions reached by Lockheed's analysts, that the catastrophic anomaly was apparently caused by a 'hard start' of the Agena's main engine, most probably resulting from a fuel rather than oxidizer lead into the thrust chamber before ignition. Unlike all previous standard Agenas, the GATV had been intentionally sequenced for a fuel lead to conserve oxidizer for the many programmed restarts. The subpanel reported its findings to the parent board on November 3.
