CASCO TOWNSHIP, Mich. – Four men have unearthed pieces of what they say is a World War II-era fighter plane that crashed 71 years ago in a southeastern Michigan farm field.

Jim Clary, his brother, Ben – an 88-year-old World War II veteran – and two other men used metal detectors to make the find earlier this month in St. Clair County’s Casco Township just east of Richmond.

The recovered fragments are from a P-38D Lightning that was piloted by 2nd Lt. Al Voss, a native of Elgin, Ill., assigned to the 94th Pursuit Squadron stationed at Selfridge air base in Michigan, Jim Clary told the Times Herald of Port Huron.
