The House Transportation and Infrastructure Committee's Subcommittee on Aviation held a hearing to discuss whether general aviation, which includes corporate and private aircraft, will be allowed to operate out of Ronald Reagan Washington National Airport. Most of the witnesses represented industry groups and were in favor of returning general aviation to the airport immediately. Elizabeth A. Haskins, president of Signature Flight Support, testified that business aviation is more secure and less threatening than commercial aircraft. James K. Coyne, president of the National Air Transportation Association, testified that general aircraft operations are willing to undertake security measures such as prescreening passengers, isolating cockpits, and having a law enforcement officer on board. Representing the Transportation Security Administration (TSA), David M. Stone testified that TSA is currently working on a security plan. But until these plans are finalized, testified Stone, general aviation will continue to be prohibited at Reagan National because such aircraft are "an attractive potential avenue for terrorists."
