无人机是无人驾驶飞机的简称由于没有飞行员.无人机可以执行超越飞行员生理极限的或者危险的任务,比如长航时、大机动飞行或者在恶劣气象条件、战场等危险区域执行任务。无人机受到世界各国青睐.与其在反恐战争中立下的赫赫战功有关。数据显示,在美军打击“基地”组织的过程中,大约有300多名被认为是恐怖分子的人死于无人机的侦察和定点清除等行动。恐怖大亨本·拉登的藏身之处就是借助无人机发现的。 Unmanned Aerial Vehicle (UAV) is the abbreviation of drones because there are no pilots. UAVs can perform tasks that are beyond the physiological limit of the pilot or dangerous tasks, such as long voyages, large maneuvers, or in hazardous areas such as severe weather conditions and battlefields. UAVs are favored by all countries in the world and are linked to their illustrious exploits in the war on terror. Data show that in the process of the U.S. military campaign against Al Qaeda, about 300 people believed to be terrorists died of drone surveillance and site clearance. Terror tycoon Osama bin Laden’s hiding place is found by means of drones.
