In 2000, a joint CIA-DoD effort was agreed to locate Osama bin Laden in Afghanistan. Dubbed "Afghan Eyes", it involved a projected 60-day trial run of Predators over the country. The first experimental flight was held on 7 September 2000. White House security chief Richard A. Clarke was impressed by the resulting video footage; he hoped that the drones might eventually be used to target Bin Laden with cruise missiles or armed aircraft. Clarke's enthusiasm was matched by that of Cofer Black, head of the CIA's Counterterrorist Center (CTC), and Charles Allen, in charge of the CIA's intelligence-collection operations. The three men backed an immediate trial run of reconnaissance flights. Ten out of the ensuing 15 Predator missions over Afghanistan were rated successful. On at least two flights, a Predator spotted a tall man in white robes at bin Laden's Tarnak Farm compound outside Kandahar; the figure was subsequently deemed to be "probably bin Laden". By October 2000, deteriorating weather conditions made it difficult for the Predator to fly from its base in Uzbekistan, and the flights were suspended.
