Fairbanks Daily News Miner “Liefer…cuts right to the meat of a usually murky situation...he has the experience, knowledge and chops not only to examine an aviation crash, but also to speculate about its cause. Readers will enjoy this book…”
Fort Nelson News “For flying buffs, this book is a must read.”
Pacific Flyermagazine, www.pacificflyer.com "…factual events of these significant disappearances are presented with meticulous insight.”
Aircraft Wreckswebsite, www.aircraftwrecks.com "Thoroughly enjoyable book that leaves the reader wanting more, well researched and focused on seventeen disappearances. Only two of these cases have been solved to date, and the others tantalize us with a myriad of questions and possibilities."
John Tippets, author of Hearts of Courage "Aviation Mysteries of the North is exceptionally well researched and a reader should appreciate the extensive use of pictures, maps and other illustrations. If you are fascinated with aviation and/or really enjoy Alaska history, you will appreciate reading this new book by Gregory Liefer." WINGS, Canada’s National Aviation Magazine, July/August 2011 "Historical perspectives and aircraft descriptions add an informative background to the stories from takeoff to the final moments." WINGS OF GOLD,The Voice of Naval Aviation, Summer 2011 "More than 100 aircraft have vanished in Alaska or Canada, or along the cold waters of the north...Included is the case of a commercial airliner carrying 38 passengers and crew, a military transport with 44 occupants, a USAF bomber carrying a nuclear payload, and two U.S. Congressmen on a campaign tour."
