Diary of a SPY

摘要

To Lockheed Skunk Works aeronautical engineer Clarence "Kelly" Johnson, the super-secret spyplane he designed in the mid-1950s was "Angel." To the Central Intelligence Agency, which used it extensively during the cold war, it was "Article." To the rest of the world, which learned of its existence when the Soviet Union shot one down in 1960 and forced the U.S. government's hand, it was a marvel. The Lockheed U-2 could fly at 70,000 feet-higher than any other aircraft had flown.
