U.S. Sen. Roy Blunt of Missouri is demanding answers about why a Southwest Airlines jet landed at the wrong airport.
Southwest Flight 4013 was traveling from Chicago's Midway Airport to Branson Airport Sunday evening. It landed instead about seven miles away at Taney County Airport, with a runway about half the size of Branson's.
No one was hurt but a passenger told The Associated Press the landing was abrupt.
Blunt, a Republican from southwest Missouri, sent a letter Tuesday to Federal Aviation Administration administrator Michael Huerta urging a complete and thorough investigation.
The National Transportation safety Board is also investigating the incident. The NTSB says it will analyze the flight data recorder and cockpit voice recorder. NTSB investigators plan to interview crew this week.
