On November 18, 1942, 2nd Lt. William Gamber lifted off from Mather Field in Sacramento, CA in a Beech 18 AT-7 with three US Army Air Forces aviation cadets - John M. Mortenson, Ernest Glenn Munn, and Leo Mustonen. They were never seen alive again. Their plane wreck was discovered in 1947 and all but forgotten until 2005 when climbers found the remains of Cadet Mustonen. Summer of 2007, the body of another cadet was discovered. FINAL FLIGHT, a book about the four aviators and their story will be published by The Wilderness Press in late 2009.
