Yeah, looks like it has been cropped out of another pic and overlaid on the shot of the 777s. They used Photoshop's "magic eraser" or whatever (been far too long since I had access to Adobe Creative Suite
) and missed a bit of something behind in the orignal pic... the triangle of the drag strut on the nose wheel is also suspiciously bright, also the scissor link. Pic's been used in the Daily Mail and elsewhere...
