It was located in Arlington, Virginia, near the intersection of the Highway Bridge and the Mount Vernon Memorial Parkway, where the Pentagon and its northern parking lots now stand.

"[2][4] Pioneering aviator Alys McKey Bryant helped clear trees and brush and run the tractor which leveled the land for the airfield.

Arlington Beach, a local amusement park, was located on the north-northeastern edge of the airport (next to Highway Bridge), and a landfill on the north-northwestern side.

[19] The United States Department of Agriculture owned the 400 acres (160 ha) Arlington Experimental Farm immediately adjacent to the northwestern edge of the field.

[22] In late 1926, the National Aeronautic Association sought to lease Hoover Field from Mitten in order to upgrade it and turn it into Washington's municipal airport.

[23] Their goal was to use Hoover Field temporarily while soil was dredged from the Potomac to create new land near Gravelly Point for a much-expanded new municipal airport.

In June 1927, the new airmail contractor for the federal government refused to use Hoover Field any longer because it was so unsafe.

[26] Hoover Field's location—bordered by highways, rivers, and federally owned land—also prevented its expansion to accommodate newer aircraft requiring longer runways.

A fire at the field on July 3, 1928, destroyed eight planes and the hangar, causing $100,000 in damages ($1.275 million in 2010 inflation-adjusted dollars).

[31][32] A few months later, on September 11, 1928, the first daily flights from Washington, D.C., to New York City began out of Hoover Field.

[37] Later that year, a plane attempting to land at night struck a car parked on the field, injuring four.

[38] The owners of Atlantic Seaboard also owned Washington Airport (see below), and for a time the two fields were operated by the same company (although not merged).

But on December 30, 1929, a group of investors led by R.H. Reiffen, chairman of the New Standard Aircraft Company, purchased Atlantic Seaboard Airways and took control of Hoover Field.

[39] Safety at the airfield improved somewhat in mid-1932, after Arlington County commissioners revoked permits for the burning of trash at all landfills in the county—including the one next to Hoover Field, but not the one next to Washington Airport.

[43] The airport added acreage and improved its facilities, and in February 1928 Funkhouser, Fahy, and the others formed Seaboard Airways.

[47] United States Air Transport was itself taken over in June 1929 by Federal Aviation Corporation, an airline based in New York City.

[48] Federal Aviation announced it was buying an additional 104 acres (42 ha) (which included the Arlington Beach theme park) for $675,000, with the goal of expanding into a six-runway airport with one runway dedicated solely to departing flights.

[51] Hoover Field and Washington Airport both suffered significant financial setbacks during the Great Depression.

[59] North American Aviation (owner of the Ludington's newly sold airline) passed on the chance to buy the property.

[65][66] It remained open as a private field for small aircraft,[67] but closed on September 16, 1941, when the United States Department of War purchased Washington-Hoover Airport for $1 million to construct The Pentagon.
