On a flight over Utah, I spotted a strange shape on the flight route app on the seat LCD that looks just like an airliner:
Not believing my eyes, I checked OsmAnd and sure enough, it's there!
Here it is on OpenStreetMap: http://openstreetmap.org/#map=11/41.27/-111.8
Pity it was clouded over, so I couldn't see it for real...
Its Wikipedia page doesn't mention its shape: http://en.wikipedia.org/wiki/Pineview_Dam
Could it be an Easter Egg or just pure coincidence?
