Early on this glorious August morning Cunard´s mighty ocean liner Queen Mary 2 arrived at Helsingør. Due to the atmospheric conditions creating a mirage effect, the ship appeared almost to float in the air as it approached its destination:

The word mirage can be more accurately defined by explaining that atmospheric conditions can cause deviation of the normally straight movement of light rays, creating a situation where an object is perceived as displaced or distorted. Mirages are usually seen at the horizon and with a very small angular diameter, yet they may take a number of shapes. The shrubs and rocks on a small island may tower into the sky; low, sloping shores may be vertically stretched so they look like precipices; a ship and its deck superstructures may distort into unidentifiable boxy shapes; entire islands seem to float in the air with inverted mirages below them; a number of mirages of the same island appear, now right way up, now upside down, above the island; a ship is seen to travel along the distant horizon upside down; the setting sun looks square, splits up into slices and gives off a final, bright green flash before going down.

On the photo below you can see the QM2 in front of Hamlet´s castle Kronborg. The mirage effect almost disappeared when the ship appears only in the more remote background:

The mirage effect is not very visible on this picture either:
