It’s always a good idea to check a map when flying a massive jet plane off into the sunset.

A Southwest Airlines flight has landed at the wrong airport, the second aircraft in two months to do so.

The commercial Boeing 737-700 jet, which took off from Chicago’s Midway International Airport bound for Branson Airport, Missouri, ended up landing seven miles away at Taney County Airport instead.

Its eventual destination has a runway half the size of the one at its intended destination, and the flight is now under investigation to find out why such a thing happened, Federal Aviation Administration (FAA) spokesman Tony Molinaro has confirmed.

Meanwhile, a spokesman for Southwest Airlines, Brad Hawkins said: “The landing was uneventful, and all customers and crew are safe. Our ground crew from the Branson airport arrived at the airport to take care of our customers and their baggage.”

It is the second time in two months that a major aircraft has landed at the wrong airport. In November, a Boeing 747 Dreamlifter bound for McConnell Air Force Base in Wichita, Kansas, ended up landing at Colonel James Jabara Airport, nine miles away. The Dreamlifter was carrying parts rather than passengers.
