i 167 President"s Board of Consultants on Foreign Intelligence Activities. At a meeting of the board on 2 February 1960, Gen. James Doolittle urged President Eisenhower to use overflights of the Soviet Union to the maximum degree possible. The President's response, as summarized in General Goodpaster's notes of the meeting, showed that the upcoming summit meeting was already an important factor in his attitude toward U-2 flights: "The President said that he has one tremendous asset in a summit meeting, as regards effect in the free world. That is his reputation for honesty. If one of these aircraft were lost when we are engaged in apparently sincere deliberations, it could be put on display in Moscow and ruin the President's effectiveness." 15 A few days later, another U-2 took to the sky on a mission over the Soviet Union. As in December, the pilot was British, and the mis sion had been ordered by Prime Minister Macmillan. On 5 Felbruary 1960, a Detachment B U-2C with squadron leader John MacAnthur at the controls left Peshawar, Pakistan, to conduct Operation KNIFE EDGE. The plane overflew the Tyuratarn Missile Test Range, headed northwest to Kazan', and then turned south, photographing long stretches of the Soviet rail network. The excellent photography from tnis mission did not reveal a single missile site, but analysts diid dis cover a new Soviet bomber. dubbed the BACKFIN, at Kazan'. 16 Despite the outcome of this mission, the missile-gap debate con tinued. The Air Force still insisted that the Soviets had deployed as many as 100 missiles . The Army, Navy, and C IA, however, doubted that any had been deployed, because none could be found . Add itional U-2 photography was needed to settle the debate. In mid-February, President Eisenhower reviewed plans for four additional U-2 mis sions. The success of the two British missions, along with the absence of Soviet protests, made the President more willing to consideir a re sumption of US overflights, and he agreed to allow one missiorn to be flown during the month of March. The President's continued riestric tions upon the use of the U-2 disturbed DCI Dulles, who sent a memo randum to the National Security Council on I March 1960 ass,erting that the cardinal objective of obtaining information on Soviet missile deployment could be better achieved if the U-2 were given freer rein."
