Its the end of a long day filled of uncooperative weather, ground stops, and a diversion tossed in to make it interesting. Youre shooting the non-precision (of course) GPS approach, and upon reaching minimums, you look up and see … nothing. Wait a minute! Isnt that a PAPI glowing out of the left side of your window? Is that your runway? If so, whats it doing all the way over there?
