p.m., a helicopter pilot with U.S. Customs and Border Protection flying over Tucson, Arizona, reported to air traffic control that he had just had a near collision with a drone. A Tucson Police Department helicopter was sent into the area and the two helicopters followed the object and attempted to determine the location of whoever might be operating it. While it was described as a drone and a quad-copter, it was mostly tracked using night vision, and the only visual description was of a blinking green light. If it was indeed a drone, it attained an altitude well above the 400 foot limit set by the FAA, performed extraordinary evasive maneuvers, and had a power source that lasted far longer than a normal drone battery.
