AAR hangar more impressive than ever

More impressive than ever, the two hangars, made up of 52,000 bolts, 1,000 tons of steel, and 200,000 square feet covered by 120 rolls of PVC cover, are the largest pre-engineered structures of their kind. The $40 million project is still on track to finish in June, according to Rockford Airport Executive Director, Mike Dunn. The South hangar is already fully covered and crews have also poured the flooring where the offices and owner suites will be.
