The Minneapolis-St. Paul Airport Trams and the airport also known as World Chamberlain Field were both constructed by whom?
Minneapolis–St. Paul Airport Trams The Minneapolis–St. Paul Airport Trams consist of a pair of cable-drawn automated people movers that serve travelers of the Minneapolis–Saint Paul International Airport. Both were constructed by the Poma-Otis Transit Company of Farmington, Connecticut and are operated under the direction of the Metropolitan Airports Commission.
Washington Airport Washington Airport was the second major airport to serve the city of Washington, D.C., in the United States. Located in Arlington, Virginia, near the intersection of the Highway Bridge and the Mount Vernon Parkway (where The Pentagon's south parking lots, Metrobus bus bays, and a portion of Interstate-395 now exist). The first airport to serve the city was Hoover Field, a private airfield constructed in 1925. Washington Airport, a private airport triple the size of Hoover Field, was built literally across the road in late 1927. The airfield suffered from short and unpaved runways, numerous life-threatening obstructions around the field, poor visibility (due to a burning garbage dump adjacent to each field), and poor drainage. Washington Airport nearly went bankrupt in 1933, and it was auctioned off to a new owner. The new owner also owned Hoover Field, and merged the two into a single airfield, Washington-Hoover Airport.
