Creamer’s Dream from Shorpy.

More than 60 years ago six P-38 Lightnings and two B-17 bombers left Presque Isle, Maine, headed for England. They never made it; instead all eight plans set down on an ice cap in Greenland. Fifty years later a group of aviation enthusiasts decided to locate the ‘Lost Squadron’ and recover one of the P-38s - from under the 25 stories of ice that had buried the planes in the intervening years

That P-38, now dubbed ‘Glacier Girl,’ was full restored and  returned to the sky.
