Plane passenger snaps photo of shadowy humanoid walking on cloud

This incredible photo, shot from a plane at 30,000 feet, captures what looks like a silhouette of the Iron Giant strutting across a cloud. When passenger Nick O'Donoghue, who was on his way back to Ireland from Austria, first saw the image, he thought he was hallucinating. But his two colleagues, sitting next to him, saw it too, so he whipped out his camera and caught these cool images.

Unfortunately, it wasn't really the Iron Giant (damn!), but more likely an optical illusion known as Fata Morgana, or a mirage, according to weather experts. Thanks Daily Mail!
