Boston Airport

Boston Airport is a location in the Commonwealth which is initially deserted but later controlled by the Brotherhood of Steel in 2287.

Layout
Before the war, the airport was composed of several runways, hangars, and support buildings. Struck by rising sea levels after the Great War, the runways and other low-lying buildings were submerged by the adjacent ocean.

The airport is comprised of a central terminal building, which is mostly destroyed, a parking garage and a small garage. There is also a tarmacked surface which bears the remains of several Horizon Airlines jet airliners. The airliners are completely destroyed, with the wings having separated and the fuselages being torn into three parts. The aircraft interiors have been completely stripped out. The tarmac is also littered with an abundance of junk.

The entire site is inhabited by feral ghouls. There is a glowing one on the top floor of the terminal. The tarmac is sunken into the bay, and mirelurks inhabit the shore. In the lowest floor of the parking garage there are two police protectrons which can be activated using the Novice-locked terminals nearby. After the completion of Reunions, the Brotherhood of Steel will establish a base at the airport, containing a helipad for vertibirds, a gantry to hold the remains of Liberty Prime and a supply depot. The Prydwen will also be anchored over the airport unless destroyed.

There is an area at the end of the terminal which contains a workshop in a waiting area, which has no roof. It can be used as a settlement but there are severe limitations:

Water purifiers cannot be built (regardless wheter or not the player has the Wasteland Workshop add-on installed) since the settlement radius doesn't extend to the water, so only pumps can be used to provide a water supply. Crops cannot be planted at all, garden plots cannot be built so food cannot be supplied even if Wasteland Workshop has been installed. No recruitment radio beacon can be built, so no settlers will join. No guard posts can be built, so the only method of defense is building turrets. Nor is it possible to build any stores, scavenging stations or artillery pieces. Therefore, there is little purpose or practicality in building a settlement here. There is plenty of flat surface within the radius, which can allow for large buildings to be constructed without obstruction. That being said the area could be built up by the Sole Survivor into an exclusive settlement located right beside Boston Airport.

The settlement is however used as part of several story line quests for the Brotherhood of Steel. Firstly as a build area to construct parts for the quest Liberty Reprimed and also as a build area to construct the signal interceptor if siding with the Brotherhood in the quest The Molecular Level.

Appearances
Boston Airport only appears in Fallout 4.

Behind the scenes
Boston Airport seems to be based on Boston's Logan International Airport, but with a number of changes. For example, the air traffic control tower that the Prydwen uses as a mooring mast seems to resemble the "googie" architecture of the Theme Building at Los Angeles International airport more than the real life Logan airport tower. Since the real life Logan Airport control tower was built in the 1970's, this is another example of the divergence between the Fallout universe and our own.
