Recovering service members lost 70 years in an Alaskan glacier

There are no white crosses amid the blue of Colony Glacier in Alaska, even though it's been the resting place for 52 U.S. servicemen, locked in frozen limbo there since 1952. It was just five days before Thanksgiving when a massive C-124 Globemaster on its way to Elmendorf Air Force Base in Anchorage lost radio contact during a storm.

On board: Eight Army soldiers, a Marine Corps major, a Navy commander, and 41 airmen, including Isaac Anderson, who left a letter to his wife behind. He'd written it two hours before he got onto the plane, said his granddaughter, Tonja Anderson-Dell.

"All I want you to do is to write me every day, and to stay sweet, and be good, and take care of my son," Anderson wrote.
