Yes, there are air traffic controllers that are watching and guiding the flights but this one slipped through the cracks.
In the future airplanes will be guided by an on-board flight computer only and the air traffic control system will be completely automated.
I wonder what the tower said when they cleared the flight to land but it never appeared...:^)
The correct airport had a tower, the one they landed at did not. It could have scared the **** out of any local pilots having a 737 appear on what was probably a straight in approach!
My guess, a visual approach, at night. The runway alignment for both airports is the same or very close. 15-20 miles out the pilot sees the beacon for the wrong airport and reports airport in sight. Is cleared for the visual approach and, following the wrong rotating beacon, lands at the wrong airport.
