Answer:
Option: an American plane was shot down
Explanation:
In the 1960s, the Soviet Union shot down a U-2 spy plane and captured Pilot Gary Francis Powers. The United States denied the aircraft used for surveillance. The Soviet, with the capture of the pilot and wreckage, declared part of the CIA. At last Dwight D. Eisenhower forced to admit that it had been spying on the Soviet. Tensions from the incident were high when Eisenhower and Russian leader Nikita Khrushchev arrived in Paris to begin a summit. Khrushchev wasted no time in blaming the United States.
