Supplementing the Chronological Files of this period are NASA Sensitive Chronological Files and the Apollo Memoranda. The Sensitive Chronological Files consist primarily of correspondence and memoranda sent, and memoranda for the record, 1967-1976. Matters recorded in these Files were considered more sensitive at the time of their discussion. During the Deputy Administrator period, correspondents include the NASA Administrator, Associate and Assistant Administrators, Center Directors, members of Congress, and the Office of Management and Budget. The Files provide reviews of current projects and events which GML drew up for the Administrator, records of internal and external meetings and telephone calls, and descriptions of ongoing efforts and strategies in such areas as: recruitment and reorganization, program and project management (including budget, configuration, procurement plans, contractor selection, and anomalies), contractor management, Congressional relations, and interagency and international cooperation. GML's 1975-1976 job search is also documented in the Sensitive Chronological Files of this period. During the Apollo Spacecraft Program Office and transition periods, correspondents include Robert Gilruth, Gen. Samuel Phillips, industrial leaders, and Program Office staff. Correspondence topics include studies of flight, manufacture and hardware anomalies, advanced Apollo missions, the organization, budget, personnel, and inter-center relations of the Manned Spacecraft Center, and agency-wide planning.
