This is the best collection of articles on UFOs that I have ever seen. The world's leading ufologists were asked to write special articles for this book. One of the best aspects of this book is it has selections by foreign ufologists. Thus it is refreshing to see new names in ufology give their point of view.
A Danish ufologist, Kim Hansen, writes about, the Coyne helicopter case that occurred over Mansfield, OH, in October, 1973. This case involving four members of the Ohio National guard and their close encounter with a UFO is a classic. All aspects of the phenomenon are covered in this book, UFO history, classic cases, all sorts of theories and explanations ranging from psychological to the paranormal. It is unlikely you will find this book in a library or book store as it is from an English publisher and not many copies were printed. This is unfortunate as it is an excellent book.
