Accordingly, Seamans asked Mueller to establish a GATV Review Board to investigate all aspects of the Agena failure, managerial as well as technical. Manned Spacecraft Center Director Robert R. Gilruth and Major General O. J. Ritland, Deputy Commander for Space, Air Force Systems Command, were designated cochairmen of the review board. Primary responsibility for determining the cause of failure lay with Air Force Space Systems Division, which would make its findings available to the board.
