Question

Quizplus · Accepted Answer

The United States and the Soviet Union were planning a summit meeting in Paris in 1960, but the Soviet Union withdrew from the negotiations after an American U-2 spy plane was shot down over Soviet airspace. The United States initially denied flying over Soviet territory, but when evidence proved otherwise, the Soviet Union demanded an apology, which the United States refused to give. This led to the cancellation of the summit meeting.
