Glories aren't usually seen from the ground, as you need to have the sun directly behind you. Until people started flying around the only way to see them was from a mountain looking down into fog; the effect is related to the 'spectre of the Brocken'. They're very easily seen from aeroplanes, though.

You can occasionally get a similar effect on dew in the early morning. If you look at the shadow of your head on wet grass, you can sometimes see a sort of halo around your head.

Here's a question for you: where was Chris sitting in the plane?
