A Southwest Airlines passenger plane made a sudden dive and flew just 500 feet over buildings before landing in the US city of Oklahoma, reported local media.
The Boeing 737-800 from Las Vegas was cleared to land at Will Rogers Airport in Oklahoma City just after Wednesday midnight. But it made a steep descent and prompted the Air Traffic Controller to sound a low altitude alert.
"Southwest 4069, low altitude alert. You good out there?" warned the ATC.
The plane passed only 500 feet over a school building but quickly regained its altitude, reported The Oklahoman. It then circled and landed safely at another runway, it added.
