Good info and pictures here plus a condensed audio from the pilots and ATC: http://www.buzzfeed.com/passantino/...y-lands-at-a-tiny-kansas-airport-and?s=mobile
I wonder if it was a precision RNAV approach? If not then I could see how this could happen. Still, in these days of moving maps and GPS I find it hard to believe this happens to the big guys.
How many of the 'big guys' use moving map GPS?
