WICHITA, Kan. (AP) — Volunteers restoring a World War II-era B-20 bomber in Wichita are racing the clock as they aim to fly the historic Superfortress at a Wisconsin air show in July.

The overhaul of the Wichita-built plane began in 2000, but was put on hold for a few years.

The project resumed in 2013 with about 50 to 60 volunteers. They’re replacing wires, cables, pulleys and skin panels corroded by salt and sand during the years the 1944 plane spent stored in California’s Mojave desert.

But more work is needed. The group is looking for more volunteers with certain skills, including aircraft electricians and sheet metal mechanics.

Once the plane is restored, the group hopes to find a permanent home for it in Wichita.
