When a new shift took over at the ARTC radar room at National Airport, the air traffic was light so only one man was watching the radarscope. The senior traffic controller and the six other traffic controllers on the shift were out of the room at eleven-forty, when the man watching the radarscope noticed a group of seven targets appear. From their position on the scope he knew that they were just east and a little south of Andrews AFB. In a way the targets looked like a formation of slow airplanes, but no formations were due in the area. As he watched, the targets loafed along at 100 to 130 miles an hour; then in an apparent sudden burst of speed two of them streaked out of radar range. These were no airplanes, the man thought, so he let out a yell for the senior controller. The senior controller took one look at the scope and called in two more of the men. They all agreed that these were no airplanes. The targets could be caused by a malfunction in the radar, they thought, so a technician was called in --the set was in perfect working order. The senior controller then called the control tower at National Airport; they reported that they also had unidentified targets on their scopes, so did Andrews. And both of the other radars reported the same slow speeds followed by a sudden burst of speed. One target was clocked at 7,000 miles an hour. By now the targets had moved into every sector of the scope and had flown through the prohibited flying areas over the White House and the Capitol. Several times during the night the targets passed close to commercial airliners in the area and on two occasions the pilots of the airliners saw lights that they couldn't identify, and the lights were in the same spots where the radar showed UFO's to be. Other pilots to whom the ARTC radar men talked on the radio didn't see anything odd, at least that's what they said, but the senior controller knew airline pilots and knew that they were very reluctant to report UFO's. The first sighting of a light by an airline pilot took place shortly after midnight, when an ARTC controller called the pilot of a Capital Airlines flight just taking off from National. The controller asked the pilot to keep watch for unusual lights--or anything. Soon after the pilot cleared the traffic pattern, and while ARTC was still in contact with him, he suddenly yelled, "There's one--off to the right-- and there it goes." The controller had been watching the scope, and a target that had been off to the right of the Capitaliner was gone. During the next fourteen minutes this pilot reported six more identical lights.
