These photos, taken from a Flickr set, show what appears to be some sort of crashed spacecraft in London's Potters Field. They offer no explanation as to what's going on over there across the pond. Do any of you know what this is? Movie shoot? Publicity stunt? Photoshoppery? Actual alien invasion? Let's hear your guesses, both educated and uneducated, in the comments. Update: It's an ad for a new car. Boo.
