This week we talk to Derek Willis who developed his own rockets in the 1990's. One of the rockets he built and launched achieved an altitude of 5km. Strange things then started to happen and his ambition to launch his own rockets into Earth orbit was thwarted. Following this Derek was approached by a publisher and asked to write a book about the history of rocketry and space flight. While researching this book he came across "myths" about spacecraft being sent to Earth from the star Aldebaran thousands of years ago. He then set about searching for evidence which might shed light on these myths and has written a hypothesis entitled "The Aldebaran Project". In the hypothesis he proposes that an ancient alien satellite may still orbit the Earth and he intends to launch a mini satellite to try and observe it and prove the hypothesis.
