This flight was also utilized to return Progran 1 instruments, the high priority of such a return being dictated by ZI test planning. Flight terminated, andload transferred to CARCO for transport to Los Alamos, at Travis. We thus see that the sample return mission was accomplished. The chain of events first indicated by the lack of Program ) samples on Flight 3E directed attention to several weaknesses in the plan outlined in the above mentioned SOP!'s that one hopes to avoid for future operations. A suggested solution to these yeaknesses is discussed under the RECOMMENDATIONS section of this report. X.
