 An American Airlines flight from Reagan National was cleared by air traffic control to land as a Delta flight was cleared to take off from the same runway. Police dash cam video captured the two jetliners on what appeared to be a collision course. They were only separated by about 700 feet. What this really is, in the official vernacular, is this is a loss of standard separation, meaning basically that two airplanes should not be this close together.
