It didn't say what type of airplane it was but...did they have a magenta line to follow? I've often had to "follow the magenta line" to find some of the little places, just to be sure I was at the right one!
Years ago (1987) a Delta mainline crew put a DC 9 into Frankfurt, KY, while looking for CVG! It was at night, in the rain, shooting an NDB approach to CVG, they popped out of the clouds, saw a lit up runway and landed...then it got intersting trying to find the gates! Luckily most of today's airplanes having glass cockpits and magenta lines to follow.
