Alan Watts | Unidentified flying objects
From cave paintings to the 20th century, evidence exists for strange craft visiting the Earth. This scientifically-based survey of UFOs looks at the technology, physics and chemistry involved, from the original "flying saucers" of the 1940s to crop circles in the 1990s.
