Caught a fantastic full-arc rainbow today after a squall passed through... it was already dimming a bit when I got the camera out, and then I couldn't remember how to set it up for "stitch assist" mode (to get a pano of the whole thing), but... this picture has an airplane in it... see? It's on final for 22L.
if you look close enough you can guess a second one above the first one!
Yes, it was doubled at one point, very visible near the bases... but that had diminished a little by the time I took the photo. I was gawking for a few minutes before I realized it was a good photo subject...
