This puzzle's theme: Looking out of a jet window in-flight.
In 1995, I was fortunate enough to snap this photograph on my return flight from California.
How to Play: To solve the puzzle, click a square you wish to move
to another square's location, and then click the destination's location.
Or, click the destination first, and then the square to be moved second.
Either way, you'll see the two squares have transposed positions.
