This undated photo of Francis Gary Powers shows him standing next to a U-2 spy plane. Powers was shot down and captured in the Soviet Union in 1960 and held for nearly two years. He was posthumously awarded a Silver Star at the Pentagon on June 15.
When an experimental U.S. spy plane was shot down over the Soviet Union in 1960, the U.S. government quickly came up with elaborate cover stories.
"The plane [Soviet leader Nikita] Khrushchev reported shot down inside Russian territory presumably is an American, single-engine jet, a U-2 reported missing on a flight along the Turkish-Russian border last Sunday," a broadcast at the time said. "The national space agency has been flying these planes, 10 of them, in many parts of the world, studying the upper atmosphere."
Iran's Bushehr nuclear power plant, shown in this International Iran Photo Agency image from August 2010, was infected by the Stuxnet computer worm — which reportedly was created in the United States.
