Boston Airport

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

Background
Before the Great War, Boston Airport serviced the citizens of both Boston and Massachusetts, connecting them to cities across the states between the east and west coast. It used airlines such as Horizon Airlines and Skylanes Air, who operated between cities such as Chicago and New York, but, according to a sign near the area where the workshop is located, the airport also handled "private flying" (i.e.: general aviation). Many people who were in the airport hanger and terminals were killed during the Great War.

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 exterior waiting area at the end of the terminal that contains the workshop. It can be used as a settlement but there are severe limitations.

Inhabitants

 * Knight Sergeant Gavil
 * Knight Lucia
 * Initiate Clarke
 * Proctor Ingram

Notable loot

 * There is a fusion core in the generators at the southeastern end of the ground floor of the terminal.
 * There is a mini nuke upstairs guarded by a glowing one.
 * There is a Fat Man in a car, near the water on the runway. From the Boston Airport fast travel location proceed east. The nose section of an airplane will be in front of the Sole Survivor. The Fat Man is located in a van on the water's edge behind the nose section.
 * Fishing tournament ad at the airport's ruins, on a magazine shelf behind the information desk terminal computer, at terminal B. Found when clearing ghouls on quest Duty or Dishonor.
 * Racetrack advertisement at the airport's ruins, next to the information desk terminal computer.
 * Supply log near the terminal and Gavil.
 * A lot of metal boxes with random scrap, ammo boxes, along with a few chem and aid boxes (not considered stealing).
 * There are three sets of BOS II T-60 power armor that can be stolen from sentries.  Once their armor is stolen, the sentries will continue to man their posts.  If the sentries are killed, they will eventually respawn with new armor.

Appearances
Boston Airport only appears in Fallout 4.

Behind the scenes

 * Boston Airport is 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 (the "real" Logan tower resembles a very large two-pole pylon sign). Since the real life Logan Airport control tower was built in the 1970s, this is another example of the divergence between the Fallout universe and our own.
 * The Boston airport's international code, BOS, may also be another reason why the Brotherhood of Steel may have been chosen to be based there, due to the relation between the international code and faction's acronym.

Bugs

 * If Wasteland Workshop is installed, trapping has been done and a Beta wave emitter is controlling aggressive creatures, and/or crafted robots are present, the start of Liberty Reprimed may allow these NPCs to clip through the workshop wall into the previously locked Prime workshop area and kill the attendant scribes. This apparently has no effect in the quest beyond temporarily interrupting Ingram's initial speech script when she runs to defend the scribes.
