Leo Mustonen is being buried today, over 63 years after he died.
There's a funeral service for him this afternoon in Brainerd, Minnesota.
Mustonen was a World War Two airman and one of four people killed in a military plane crash in November of 1942.
His remains were found last October mostly encased in ice in a remote mountainous section of California's Kings Canyon National Park.
Mustonen was 22 years old when he died.
He'll be buried next to his parents.
