PETERSBURG, W.Va. — Officials say ground crews are working to reach a plane that went missing days ago along the Virginia-West Virginia border.

West Virginia Civil Air Patrol spokesman Jeff Schrock said in a release Thursday night that a helicopter operated by the state police spotted the plane in a mountainous area of Hardy County, about 15 miles south of Moorefield. But crews on the ground today were still working to reach the plane.

Three people were on board when it dropped out of radio and radar contact on Sunday night, 12 miles south of the Grant County Airport in Petersburg, but their conditions are unknown.

Family members have identified those on board as pilot Michael Garrone of Allegheny Township, Pa., 52-year-old Chas Armitage Jr. of Parks Township, Pa., and his girlfriend, 49-year-old Laura Stettmier.
