Officials agree that big changes are necessary to prevent the record delays of 2007 from becoming the norm. Robert Poole, director of transportation studies for the libertarian-oriented Reason Foundation, suggests privatizing air traffic control. FAA officials want to migrate from the current radar-based system to one that uses satellites to track planes, allowing greater precision and increased capacity. Transportation Secretary Mary Peters says a solution needs to be implemented soon. "Aviation delays will grow without significant reforms as forecasters predict that air traffic will increase by the equivalent of two major hubs a year," Peters said.
