Vertical Card Compass Mystery

[Rosspilot]

A strange thing has happened that I cannot explain. I wonder what the
readership thinks . . .

I have a Precision vertical card compass. I fly at least 3 times a week, and I
know my airplane real well. Last week, when I looked at my compass, the little
airplane
that should point up was about 30 degrees left. The compass was working just
fine, but somehow the glass lens with the airplane had rotated left.

I tried to rotate it back myself--it would not budge. I know I could take the
whole compass out and put it back but how in the world could this happen?

maybe it rotated due to the vibration of the engine while you were flying
and didn't notice it.

I thought of that--but if I was physically unable to rotate the glass with all
my energy focused on doing that, I can't see how it could vibrate into that
position.
But who knows? . . . <sigh>

Probably had something to do with pre-election campaign advertising.
