UNDATED: (FILE PHOTO) This undated photo from the Lockheed Martin corporation shows the U-2 reconnaissance aircraft. The U-2's unusually long wingspan allows the aircraft to fly like a glider for long distances at high altitude to gather intelligence information such as ground surveillance. According to the United Nations a U-2, operated by the United States but baring markings of the United Nations was flown over Iraq on February 17, 2003 in conjunction with United Nations weapons inspections.
