In 1955, the Skunk Works received a contract from the CIA to build a spyplane known as the U-2 with the intention of flying over the Soviet Union and photographing sites of strategic interest. The U-2 was tested at Groom Lake in the Nevada desert, and the Flight Test Engineer in charge was Joseph F. Ware, Jr. The first overflight took place on July 4 1956. The U-2 ceased overflights when Francis Gary Powers was shot down during a mission on May 1, 1960, while over Russia.
