Info from Southwest
Now that things have calmed down, I have some more info for you. There was no advance notice of any problems, and the tire burst upon landing. The crew did not declare an emergency prior to landing. A lof of speculation may have been fueled by the one television station that was at the airport with cameras running at the time of landing, but they had no advance notice. Another television station, the ABC affiliate, had its helicopter returning to the airport at the time of landing. The aircraft was N371SW, which is currently out of service. It will not return to service until it is thoroughly inspected.
