Over at Museum of Hoaxes, Alex has posted two photos taken through airplane windows. He says: "One of these might be fake. Can you guess which?" Maddeningly, he hasn't told us which one is fake (by that, I am guessing he means there's no Photoshop trickery involved and that they are unretouched photographs).
Perhaps neither one is fake. In the comments section, one reader says the giraffe is probably a cutout of a photo that's been taped to the window. The shadow cast by the giraffe is a giveaway, he says.
And the other photo of the man with his legs sticking out of the engine might have been taken on the ground, says one reader. What looks like clouds could be snow on the runway. Link
