On May 1, 1960, the situation changed. On the eve of the Paris Summit and during the May Day holiday, CIA pilot Francis Gary Powers took off from a base in Pakistan bound for another base in Norway, with his planned flight path transgressing 2,900 miles of Soviet airspace. Near the city of Sverdlovsk Oblast in the Ural Mountains, Powers' plane was shot down by a Soviet surface-to-air missile. Powers ejected and parachuted safely to the ground, where he was captured by the KGB, and held for interrogation. The plane crashed, but parts of it were recovered and placed on public display in Moscow as evidence of American deceit.

Although the capture of Powers provided the Soviets the concrete proof that the United States had been conducting the flights, it was not immediately clear what the impact would be for the Paris Summit. At first, and before they had confirmation that Powers had survived, U.S. officials claimed that the U-2 had been conducting a routine weather flight but experienced a malfunction of its oxygen delivery system that had caused the pilot to black out and drift over Soviet air space. On May 7, however, Khrushchev revealed that Powers was alive and uninjured, and clearly had not blacked out from oxygen deprivation.
Moreover, the Soviets recovered the plane mostly intact, including the aerial camera system. It became instantly apparent that the weather survey story was a cover-up for a spy program. Khrushchev had publicly committed himself to the idea of “peaceful coexistence” with the United States and the pursuit of détente, so from his perspective, if U.S. President Dwight Eisenhower denied any knowledge of the spy program and the United States apologized, he would have continued the summit.
