Two Southwest pilots have now been grounded, after making a potentially deadly landing Sunday night.
The pair mistook a small airport in Taney County, Missouri, for the larger Branson Airport, just seven miles away.
There were 124 passengers on board the plane when it landed on a runway about half the length it should have been.
The pilots had only half as much room as normal to stop the plane.
CNN's Rene Marsh has all the details.
