He tended to favor the classical form of espionage, which relied on agents rather than technology. 1s At this point, the summer of 1954, L ockheed's CL-282 proposal still lacked official support. Although the design had strong backers among some Air Force civilians and CIA officials, the key decisionmakers at both· Air Force and CI A remained unconvinced. To make Kelly Johnson' s revolutionary design a reality, one addit ional source of support was necessary: prominent scientists serving on gov ernment advisory boards. SCIENTISTS AND OVERHEAD RECONNAISSANCE Scientists and engineers from universities and private industry had played a major role in advising the government on technical matters during World War II. At the end of the war, most of the scientific ad- visory boards were disbanded, but within a few years the growing te_n_sions of the Cold War again led governmen t agencies to seek sci- entific advice and assistance. In 1947 the Air Force established a Scientific Advisory Board, which met periodically to discuss topics of current interest and advise the Air Force on the potential usefulne:ss of new technologies. The following year the Office of Defense Mobilization established the Scientific Advisory Committee, bU1t the Truman administration made little use of this new advisory body.=-• DC/ Allen W.
