Francis Gary Powers crash landed his U-2 in the Soviet Union on May 1, 1960. Many believe that the crash was caused by sabotage by Pentagon right-wingers who were attempting to embarrass Eisenhower and stop the Paris Summit planned between Eisenhower and Khrushchev. That summit might have led to nuclear arms reductions and a lessening in Cold War tensions. Eisenhower was almost certainly lied to by the Pentagon, and when he announced the official American position was publicly embarrassed by Khrushchev, who could prove that Eisenhower's statements were a lie. It was very odd that the plane came down - it flew too high to be shot down by the Soviets - and very odd that Powers didn't take the required steps to kill himself and destroy the plane and its contents (the Soviets recovered everything). Powers eventually died in a 'accident' when the fuel gauge on the helicopter he was flying was tampered with, causing him to be unaware that he had no fuel.
Air Force Maj. Duane Dively died on June 22, 2005 in a mysterious U-2 crash in the United Arab Emirates. Although the official story was that he had been on a mission in support of American troops in Afghanistan, it isn't too much of a stretch to conclude that he was really spying on Iran. By far the oddest part of this story is that we're hearing about it. The reason we don't hear too many U-2 stories is because such espionage is supposed to be a secret. I can't help but wonder if this isn't another reflection of the neocon-paleocon battle going on in Washington over whether the United States should start World War III in the Middle East in order to please Israel. Is the crash a signal that somebody doesn't like the secret neocon preparations for war? The one thing that Iran learns from the release of this story is that it is being monitored by U-2 spy planes.
