Incident/Accident: Two aircraft. One runway. And one very close call. In May 2007, a SkyWest flight landed in San Francisco and taxied across the path of a Republic Airlines flight cleared for takeoff. In the nick of time, an air-traffic controller noticed that the planes were on a collision course and said, "uh, SkyWest HOLD HOLD HOLD," according to the NTSB. The Republic Airlines plane lifted off, and flew over the SkyWest plane. The SkyWest crew estimated there was as little as 30 feet between their flight and catastrophe. "At SkyWest Airlines,” a spokesperson said, “the safety of our passengers and our people is always top priority.”
