Honestly, I'm surprised you find this that unusual.
In my experience - which is little compared to many here - I have at least
read about enough of these types of cases that, even though I admit it's not
the FIRST thing I would think of, the possibility of sighting the wrong
airport is a real one.

I am often surprised to see how often two or more airports are situated within
a few miles of each other, and when I see it I do wonder how often pilots
break out and dive for the first one they see - though fortunately most
"wrong airport" scenarios do not end in any greater disaster than a bruised
ego.
