The Meadowlands are anchored by two airports, Teterboro at the top, and Newark at the bottom, both built on filled-in swamp, and operated by the Port Authority of New York and New Jersey. Teterboro is a reliever airport, which draws smaller and slower aircraft traffic from the three other airports (Newark, LaGuardia, and JFK). As a result, Teterboro is one of the busiest small jet airports in the nation. Sony Aviation, for example, has a hangar and aircraft fleet for celebrities and VIPs, with limos waiting to take them into New York City, only 12 miles away. Dassault Falcon, the French business jet company, has its main business office for the Americas here. Teterboro, opened in 1919, is the oldest airport in the area.
