No one in the White House, the CIA, or the Air Force could reveal that U-2 photographs had actually provided the primary evidence for this change in the estimates. $ ^{41} $
The need to keep the existence of the U-2 program secret caused problems even within the CIA itself. The Office of Security sharply restricted the number of persons who could be cleared for access to U-2 photography. The special clearance was granted on a "slot" basis, and only the person assigned to a particular position or "slot" could have the clearance. The U-2 photographs were kept in a secure room, and only those with special clearances were admitted to the room. In addition, the Office of Security considered U-2 information too sensitive to use in CIA publications. As a result, many analysts did not have access to information that would have greatly aided the production of intelligence estimates. $ ^{42} $
## TACTICAL INTELLIGENCE FROM U-2s DURING THE SUEZ CRISIS
Although U-2s had ceased flying over the Soviet Bloc because of President Eisenhower's standdown order, they could still be used elsewhere in the world. The Middle East would be the next area for U-2 operations. On 26 July 1956, Egyptian President Gamal Abdel Nasser nationalized the Suez Canal Company in retaliation for the decision by the United States and the United Kingdom to withdraw financial support for the Aswan Dam project. Nasser's action provoked an international crisis that would have a permanent effect on the U-2 program.
Long before the Suez Crisis developed, the CIA had planned to deploy U-2s in Turkey for use in the Soviet overflight program. On 1 May 1956, US Charge d'Affaires Foy D. Kohler approached Turkish Prime Minister Adnan Menderes on this matter. He told the Prime Minister that the effort was a continuation of the GENETRIX program, during which balloons had been released from Turkey, and involved aircraft that could fly 10,000 feet higher than any Soviet plane. Menderes gave his approval immediately. At the time of the Not linked to a story yet.
