VIII test periods, therefore, were over and above interim requirements, Inasmch as these augmentation personnel were on temporary duty with the 935th Air Base Squadron, their station of assignment was Kirtland, rather than Indian Springs. In September 1956, personnel to man the 9S52nd Support Squadron were requisitioned upon the assumption that Operation PLUMBBOB would start about 1 February 1957. Following organization of the 950th Test Croup (Nuclear), however, definitive PLUMBBOB information began to appear, The 950th, therefore, requested that the Center readjust by 30 days all reporting dates of personnel for the 952nd Support Squadron, These dates were changed, and all Air Force units levied upon were advised of the change. When starting date for Operation PLUMBBOB was again delayed, a second attempt was made to delay personnel reporting dates. This attempt, however, was not successful, and personnel began to arrive at Kirtland Air Force Base in December 1956, These men could not be used effectively within the 950th or the 9S52nd Support Squadron during the months before the beginning of PLUMBBOB, therefore, they were loaned to various units at Kirtland until needed in the test program, Peak personnel strength in the 950th during PLUMEBOB was as follows: Officers Headquarters,950th Test Gp.
