How do you not follow proper procedures, not follow frequencies and end up landing at an airport over 20 miles away? I mean it is beyond me that a flight crew and screw up so bad that they land at the wrong airport. As a passenger on a commericial airplane I would be extremely leary about a flight crew that lands at the wrong airport, and did not even know it until they were on the ground. It is an embarrasement to TWA, and and embarrasment to all the technology that is being used today. If those pilots can't find the right airport, with all the electronic navagation, etc., etc., how do you feel about them in an emergency situation or if they had to react quickly to a avoid an emergency situation.
