Although the U-2 overflights of Eastern Europe in late 1956 caused renewed Soviet protests, the sharpest protest came on 15 December 1956, after three specially modified USAF RB-57D bombers photographed the city of Vladivostok in a high-speed dash over the Far Eastern coast of the Soviet Union (as part of the Air Force's Operation BLACK KNIGHT). President Eisenhower had approved the mission after being told by the Air Force that the high-speed RB-57Ds would probably not be detected. $ ^{66} $
Reacting strongly to the Soviet protest, the President told Secretary of State Dulles on 18 December that he was going to "order complete stoppage of this entire business." As for a reply to the Soviet protest, Dulles said, "I think we will have to admit this was done and say we are sorry. We cannot deny it." Dulles noted that "our relations with Russia are pretty tense at the moment." Eisenhower agreed, noting that this was no time to be provocative. He then instructed Colonel Goodpaster to call Secretary of Defense Wilson, Joint Chiefs of Staff Chairman Radford, and DCI Dulles to order: "Effective immediately, there are to be no flights by US reconnaissance aircraft over Iron Curtain countries." $ ^{67} $
Flights along the borders of Iron Curtain countries continued, however, and, on 22 December 1956, Detachment B flew the first mission (4019) by a U-2 equipped for electronic intercept. The electronic-detection equipment known as the System-V unit (see appendix C) was installed in the bay normally used by the main camera, and the plane flew along the Soviet border from the Black Sea to the Caspian Sea and on to Afghanistan. The System-V unit worked well. $ ^{68} $
Early in 1957, a mission along the Soviet border accidentally turned into an overflight. On 18 March 1957, a U-2 collecting electronic intelligence along the Soviet southern border entered Soviet Not linked to a story yet.
