There have many upgrades to Concord Regional Airport so that it can handle 737s. But before it can be used by larger jets, the airport needs a taller air traffic control tower. Airport officials plan to spend $3 million for a new tower with the help of a $150,000 grant, the Independent Tribune reports. Airport Director Dick Lewis is requesting the city of Concord provide a required 10 percent match to get the grant. The airport serves corporate jets and small, private planes. Many of the aircraft are associated with NASCAR teams. The airport promotes itself as "the best way in and out of Charlotte" even though Charlotte-Douglas International Airport is located in the city of Charlotte.
