20 February 1959: CSB 24/Item 2(b) Survey of Operation of the HYDRA System

A survey of the HYDRA system was also undertaken in late 1958, and in December 1958, a report by D Sigs determined that the army communications center “be relieved of its function of acting as a ‘post-office’ for special mail from CBNRC.” Abuses of the precedence system were also noted and remedied.
