Author Bill Chalker is a scientists and a leading UFO researcher.  Here he presents the evidence of police, pilots, top public servants, missionaries, scientists and other credible witnesses. What was the strange craft that followed pilot Frederick Valentich until he disappeared over Bass Strait in 1978? Is the Australian military hiding evidence and wreckage of  UFO crashes at a secret installation in Salisbury in South Australia? Who or what abducted Kelly Cahill and two other women outside Melbourne in 1993? Why was the Drury UFO film deleted after the government handed it over to American Intelligence?  There’s also many true stories of ordinary Australians whose inexplicable experiences have changed their lives. In some cases they produced trauma, breakdown and even death, but in others there was enlightenment and personal transformation
