 Two planes nearly collided in the skies over Syracuse, New York. Police dash cam video capturing an American Airlines regional jet moments from touchdown, forced to go around as a Delta Connection flight took off on the same runway. When we were descending, there was another plane leaving the runway, so we had to divert and go around Syracuse. The jets coming less than 1,000 feet vertically from each other. The pilot asking controllers who was cleared for the runway.
