BRENTWOOD, Calif. (KCBS/CBS 5)  -- If you spot a 22-foot long replica of the Navy dirigible USS Macon drifting through East Bay skies, a Brentwood family wants it back.

Jack Clemens has spent the last five years building an exact scale model of the Navy dirigible that was moored at the huge hanger at Moffett Field in the 1930's.

His wife Pat says her husband took the remote control airship out for a spin Thursday morning and a gust of wind blew it away. She says it was spotted by farm workers and a Contra Costa County sheriff's deputy heading towards Discovery Bay and Tracy.

The craft is made of gray mylar and balsa wood, and has eight electric motors. It was painted with blue and white stripes and the words USS Macon.

Mrs. Clemens says her husband, who spent hundreds of hours building the craft, had just received word he would be able to show the airship in the hanger a Moffett Field, something he's worked to do for years.

Mrs. Clemens says this is actually the second model her husband has built. The first one was ruined when their cat jumped on it.

The real USS Macon crashed off Pt. Sur in 1935, killing 2 crew members.

Anyone that spots the Clemens’ replica should contact the Contra Costa County Sheriff’s Office.
