The latest standoff has sparked international hysteria. But the more countries know about friends and enemies, the better

Long ago, in May 1960, an American U-2 spy plane took off from Pakistan to fly at high altitude across the Soviet Union as part of a mission to photograph key facilities and military sites on behalf of the CIA. The Russians saw it and shot it down. The pilot, Gary Powers, managed to descend by parachute and was arrested. In Washington, the Eisenhower administration lied about his mission, claiming the U-2 was a weather plane" that had strayed off course after its pilot had difficulties with his oxygen equipment" (sound familiar?).

The incident caused a temporary poisoning of US-Soviet relations as the Kremlin turned it into political theatre. Moscow subjected Powers to a highly publicised criminal trial and gave him a 10-year sentence.
