On November 18, 1942, an AT-7 navigational training plane left Mather Airfield in Sacramento, California, carrying four airmen (the pilot and three cadets) and about five hours of fuel. The plane never returned.
Although authorities searched for over a month, no sign of the plane was ever found until November 1947 when the wreckage was discovered by hikers on Darwin Glacier in the Sierra Nevada. The hikers, however, did not find the bodies of any of the airmen. They were 2nd Lt. William A Gamber, 23, of Fayette, Ohio (pilot) and the three cadets, Ernest Munn, 23, of St. Clairsville, Ohio; John Mortenson, 25, of Moscow, Idaho; and Leo M. Mustonen, 22, of Brainerd, Minn.
In October 2005, two ice climbers discovered the remains of one of the airmen. As reported by CBS News: the climbers told authorities that they saw "a frozen head, shoulder and arm while climbing the glacier on the side of 13,710-foot Mount Mendel in the Sierra Nevada on Sunday [October 16].... The body was 80 percent encased in ice, and still wearing an Army-issued parachute. Officials say the man's torn sweater reveals skin, and parts of his sandy-blonde hair are still intact."
When the body was found, information about the 1942 crash was so sketchy that various news organizations reported that the bodies of four airmen had been found in 1947 (when the wreckage was discovered). They also indicated that a body (the one discovered in 2005) had been missed in 1947. These reports were erroneous, however, since no bodies were ever recovered from the crash until 2005. Only four people were on board the AT-7
