Southwest Airlines flight lands at wrong airport While the plane landed safely, M. Graham Clark has a far shorter runway than Branson - 3,738 feet rather than 7,140 feet - and one passenger claimed on Twitter that the aircraft came to a halt close to the end of the runway. "Our ground crew from the Branson airport has arrived at the airport to take care of our customers and their baggage," said a spokesman for Southwest Airlines. The landing was uneventful, and all customers and crew are safe Tony Molinaro, a Federal Aviation Agency spokesman, said it was investigating the mistake. Other airlines have been involved in similar incidents. In November last year a Boeing 747 carrying cargo caused chaos mistakenly landing at a tiny airport instead of a large military base nearby. In May a Ryanair flight to Kefalonia was diverted to an airport 200 miles away because the pilot said it was "too dark to land." The world's largest low-cost carrier, Southwest Airlines is described as the US equivalent of Ryanair. Michael O'Leary, Ryanair's chief executive, has previously said he was inspired by Southwest's business model.
