"Historically, the greatest use of UAVs has been made in the areas of intelligence gathering, surveillance, and battle damage assessment (BDA), where they allow armed forces to avoid placing pilots at risk. They have also been used to gather nonmilitary information in environments that are hazardous to human beings. For example, B-17 bombers were adapted to fly by remote control during the Bikini Atoll nuclear bomb tests. The Israelis have also used UAVs extensively for reconnaissance purposes. During the Gulf War, the coalition allies used them for intelligence and BDA purposes. In fact, the Pioneer UAV was praised as "the single most valuable intelligence collector" in the war against Iraq. They have proved to be extremely reliable and have had high mission completion rates. During the Gulf War, only one UAV was lost in more than 300 missions."
