Illustrated data on construction of 257 ft span, thin concrete shell hangar at Chicago airfield; form problem was solved by use of traveling timber framework about 60 by 250 ft in plan, mounted on 10 rails transverse to span; plywood nailed on purlins served as form surface; screw jacks permitted accurate vertical adjustment to arch curve; description of jacking operation.
