Paine Field , also known as Snohomish County Airport, is a commercial and general aviation airport serving the Seattle metropolitan area in the U.S. state of Washington. It is located in unincorporated Snohomish County, Washington, between the cities of Mukilteo and Everett, about north of Seattle. PAE covers of land. The airport was built in 1936 by the Works Progress Administration and began commercial service in 1939. It was named for Topliff Olin Paine in 1941, shortly before the Army Air Corps began the occupation of Paine Field for military use. The airport briefly returned to civilian use in the late 1940s, before conversion into an air force base during the Korean War. In 1966, the Boeing Company selected Paine Field for the site of its Everett assembly plant as part of the Boeing 747 program. By the 1970s, the airport had grown into a hub for light aviation and manufacturing, lacking commercial service. The county government sought to begin commercial service at Paine Field as early as the 1980s but was halted by opposition from neighboring cities. In March 2019, Paine Field resumed commercial service at a newly constructed terminal. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2019–2023, in which it is categorized as a national reliever airport facility. Description Paine Field has two runways: 16R-34L and 16L-34R. 16R-34L, at in length, is suited for the majority of aircraft and sees occasional heavy traffic. The first 1,000 feet of runway 16R is concrete, while the remainder is asphalt. It is in very good condition. Runway 16L-34R is in length, and suitable only for small aircraft. Its pavement is in fair condition, with a noticeable rise in elevation mid-field, when compared with the ends. Runway 11-29 was decommissioned on September 10, 2020, and Boeing is leasing some of the former runway space to park partially completed aircraft. The Paine (PAE) VOR/DME is located on the field. It is unusually mounted on top of a Boeing hangar. The airport has 456 general aviation hangars, of which 326 are leased by the County, and 130 are "condominium" hangars. Wait time for a hangar currently ranges between 6 months and 5 years, depending on type. Paine Field is home to the Boeing Everett Factory, the world's largest building by volume, and the primary assembly location for Boeing's wide-body 747, 767 and 777 aircraft. Paine
