SIERRA VISTA, AZ - OCTOBER 30:  The new MQ-9 Predator B, an unmanned surveillance aircraft system, unveiled by the U.S. Customs and Border Protection (CBP), takes off at Libby Army Airfield at Ft. Huachuca October 30, 2006 in Sierra Vista, Arizona. CBP will use the new MQ-9 Predator aircraft to patrol the southern border of the United Sates in order to stop the illegal entry of thousands of Mexican nationals and drug runners who use the vast expanses of the Sonoran desert to cross into southern Arizona, daily. The new unarmed plane flew briefly for the press to show off its surveillance  capabilities by pilots of the contractor, General Atomics Aeronautical Systems. Agents of CBP will start training on the use of the aircraft very soon. The Predator will start full scale flight operations along the Mexico-Arizona border today.
