UFOs through time.

Sorry for the recent Torygraph binge here on the blog, but this is rather good fun. A history of photographs of UFOs. Parts II and III here. Over 140 years old Fakes, something else, or proof of life outside the Lab? Remember a UFO is only unidentified and not necessarily little green (or pink?) men from Mars. Who knows. But worth a click through. A nice illustration of photographic techniques over time too. I suppose, if nothing else, it's an evidenced history of unknowns. Could be the basis of a history book even Donald Rumsfeld might read?
