These requirements were to be included in the next revision of the overall test and checkout requirements documents at KSC. (Burns' action came largely as a result of discussions at the AS-503 Crew Safety Review Board meeting at KSC on August 20-21, 1968.) Burns recommended that KSC prepare a contingency plan specifying various stage and launch vehicle test and checkout procedures that would satisfy MSFC's requirements. The most immediate assessment must be the overall safety of the launch vehicle. Electronic and electrical components headed the list of specific hardware systems to be assessed.
