I really cannot remember if this was at Washington Dulles or Chicago airport, anyone?
UPDATE: as a few people have pointed out in the comments, this is actually in Chicago. I changed the title of the post, but the wrong title will remain on teh photo, you will need to ignore this :)
Anyway, it was during a trip with many stopovers a few years ago and here I had to wait a few hours extra as a giant thunderstorm successfully tried to keep all planes grounded. While everybody was looking sleepily at their feet and at the numerous Delayed notices at the screens, I was watching the planes outside and suddenly saw this rainbow appear for only a minute or so, perfectly framing the United Airlines plane that was taxiing…
I am not advocating flight travel and always try to offset my polluting actions, but sometimes the combination of nature and those who are destroying her come of with visually surprising combinations :)
