Aerospace is one of the few remaining manufacturing industries in which America is No. 1, and it's the largest net exporter of any industry — contributing more than $40 billion to our trade balance. The world comes to us for commercial and military aircraft, rockets and other space equipment and a wide assortment of related parts and services. But competitors are licking their chops and ready to pounce, as they did in so many other areas in recent decades. Government-owned aerospace companies in China, for example, would be thrilled if Congress forces our plants to close and our suppliers to go bankrupt.
