What exactly are UFOs? Are they aliens, military aircraft or easily explained phemomena? Mike Watkins tries to get to the bottom of the subject, looking into UFO sightings throughout history and by analysing sightings he had in Stroud and Gloucester a number of years ago. Stroud FM presenter Paul Farrar recalls an encounter he had with a UFO and Chad Wornfoot reports on some fascinating local sightings reported in recent years. Music from Little Angels, Hawkwind, Joe Satriani, Monster Magnet and Oasis.
