They Live in the Sky | Invisible Incredible UFOs Around Us

Constable's first full-length book reissued, which reveals otherwise hidden creatures and objects traversing our skies that were exposed with his groundbreaking infrared photo techniques. Also covered is a series of telepathic communications the author had developed with what was claimed to be an extraterrestrial intelligence. He abandoned this line of research in future work because much of the information received could not be fully verified, and he felt that delving into it more deeply could affect his other work on important scientific levels. Therefore, this book is entirely unique - mapping out a serious scientific pursuit of hidden beings and objects in our atmosphere with the experience of strange, telepathic communications. This book also references the work of the main UFO researchers of the time including Major Donald Keyhoe, George Adamski, Harold Wilkins and George Van Tassel. Includes 36 original photos by Constable, accompanied by a chapter devoted entirely to their study.
