Eyes on Saddam
The ability of the United States to gather overhead imagery of targets in foreign nations has evolved dramatically over the last sixty years. Modified bombers and fighters used in World War II and the early years of the Cold War gave way to specialized reconnaissance aircraft, such as the U-2 and SR-71, and to a variety of satellite systems. The capabilities of satellite systems have also evolved dramatically over the last four decades - from satellites that returned film days or weeks after the images were obtained to satellites that return their imagery virtually instantaneously.
