Plane passengers got quite the surprise Sunday night when they learned they had landed at the wrong airport.

Southwest Airlines Flight 4013 was scheduled to land at Branson Airport in Missouri, but instead, it arrived about seven miles away at Taney County Airport.

The airport, which wasn’t even open at the time, services smaller planes and commercial jets. The plane landed on a runway about half as long as it should have been.

There were more than 100 passengers aboard the plane.
