Pilot Starts Takeoff WITHOUT Clearance at SFO… Controller Stops It

An Aeroméxico Boeing 737 operating Flight 623 at San Francisco International Airport (SFO) began its takeoff roll before receiving takeoff clearance from Air Traffic Control. The tower had instructed the aircraft to “hold position” while another aircraft was on final approach — but moments later the jet started accelerating down the runway anyway. Controllers immediately noticed the movement and quickly instructed the crew to cancel the takeoff. The pilots performed a rejected takeoff at low speed and exited the runway safely. This incident highlights how quickly situations can develop on a busy runway — and why clear communication between pilots and ATC is critical for aviation safety.
