This picture is the perfect example of why you should always take the window seat on a flight! This stunning landscape (or skyscape?) was snapped as passenger Mark Hersch's flight was approaching Chicago O' Hare International Airport last week. He had his iPhone out to take a picture when the plane took a sharp turn and revealed this incredible sight – the Chicago skyline casting its shadow on the surface of Lake Michigan. One physicist even drew a design explaining the lines of perspective that went into the image, which you can check out here. This mystical photograph is definitely a once-in-a-lifetime shot. (via)
By the way - can you spot the second aircraft in this photo?
