The C.I.A. and the U-2 Program, 1954-1974 [EPUB ebook] 

This is the complete formerly Top Secret record of the C.I.A. and the U-2 spy plane program. The U-2 was a spy plane that could fly at 70, 000 feet, above the radar of any other country. To build such an aircraft was a daunting task. But on May 1, 1960 , one U-2 was shot down over Russia; pilot Francis Gary Powers was put on a ‘show trial’ in Moscow. The incident fractured U.S. – U.S.S.R. relations. 265 pages, plus Bibliography.
