In this March 28, 2014 photo provided by the U.S. Air Force, members of the 348th Reconnaissance Squadron monitor the flight of an RQ-4 Global Hawk during an endurance flight from Grand Forks Air Force Base, N.D. The flight set a new record, lasting 34.3 hours. It was the longest flight without in-air refueling for a military aircraft and broke the record by a little more than an hour. Additionally, the mission was staffed entirely by female Airmen in recognition of Women's History Month. (AP Photo/Courtesy of the U.S. Air Force, Staff Sgt. David Dobrydney)
