Touchdown! Greaser!
Like Russ said, it’s a strange case, but I’ve done it once. NDB approach, I think it was Watertown, Wisconsin. It had snowed overnight, everything was white, including the plowed runway. I was below the clouds in good visibility, but was almost over the airport before I could pick out the runway. Circling mins were the same as straight-in, so I circled to the same runway.
It was actually my second attempt at the approach, since I couldn’t spot the runway the first time, and when I got below the clouds I used a sectional chart to figure out exactly where to look for the runway.
