Boston Airport

The Boston Airport, or Boston International Airport, is a location and potential settlement in the Commonwealth

Background
Before the Great War, Boston International Airport served as a hub for both domestic and international flights. Airlines such as Horizon Airlines and Skylanes Air operated here, providing service to cities such as Chicago and New York and according to a sign near the area where the workshop is located, the airport also handled "private flying" (for example, general aviation or charter flights). Many people who were in the airport hangar and terminals were killed during the Great War.

It is initially deserted but later comes under the control of the Brotherhood of Steel. While the Prydwen remains moored at the control tower, the airport has been repurposed as a logistics center. Everything the Brotherhood needs to operate passes through here: supplies from the Prydwen, salvage from the field, everything. Access is strictly limited and every inventoried element is tracked down to every single bullet and bolt.

The Boston Airport serves as a forward operating base for all operations in the Commonwealth. Supplies are stored here, as well as the remains of Liberty Prime, who the Brotherhood plans to rebuild and use against the Institute. The Brotherhood's best soldiers are stationed as the last line of defense for both Prime and the Airport itself, with even Star Paladins encountered patrolling the walkway surrounding Prime. Behind Prime's building platform is the storage depot, where Knight Sergeant Gavil stores all incoming rations appropriately and supplies gear to field soldiers. Above that is a landing platform, where a general recreational area lies around it. Benches, vending machines, and several food items lie about to allow the Brotherhood to relax with each other before heading out.

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 tarmac bearing the remains of several Horizon Airlines airplanes. The airliners are completely destroyed, with the wings separated and the fuselages 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. On the lowest floor of the parking garage, there are two police Protectrons which can be activated using the Novice-locked terminal nearby. After the completion of the Reunions quest, 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.

Settlement
The settlement is used as part of several storyline 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.

If the Sole Survivor makes enemies of the Brotherhood of Steel, the Sole Survivor loses control of Boston Airport as a settlement. The settlement cannot be regained until the Prydwen is destroyed through either Rockets' Red Glare, Airship Down, or With Our Powers Combined. The airport ruins must also be cleared of feral ghouls. Otherwise, when attempting to use the workshop, the message "You cannot use this workshop yet" appears.

Additionally, any settlement defenses built and in range of Brotherhood troops will remain allied with the Sole Survivor and against the Brotherhood, in spite of losing the settlement.

There is an exterior waiting area at the end of the terminal that contains the workshop. It can be used as a settlement, but with severe limitations. Several settlement objects cannot be built, such as:
 * Water purifiers cannot be built, since the settlement radius does not extend to the water. Only pumps can be used to provide a water supply.
 * Crops cannot be planted nor can garden plots be built.
 * A recruitment radio beacon cannot be built.
 * Guard posts and artillery pieces cannot be built. The only way to improve settlement defense is to use turrets. However, Vault-Tec-type guard posts can be built if the Vault-Tec Workshop add-on is installed.
 * Stores and scavenging stations cannot be built.

Inhabitants

 * Knight Sergeant Gavil
 * Knight Lucia
 * Initiate Clarke
 * Proctor Ingram
 * Madison Li (optional)
 * Professor Scara (optional)

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 guarded by a glowing one on the top floor of the terminal, just above the workshop.
 * 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 in a van on the water's edge behind the nose section.
 * Racetrack advertisement at the airport ruins, next to the information desk terminal computer.
 * Fishing tournament ad at the airport ruins, on a magazine shelf behind the information desk terminal computer, at terminal B. Found when clearing ghouls during the quest Duty or Dishonor.
 * Lucia's personal key on Knight Lucia. It opens her footlocker aboard the Prydwen.
 * Supply log near the terminal and Gavil.
 * 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.

Companion comments

 * When at this location companions make comments, which are activated before the barricades, both before and after the Brotherhood arrive. X6-88 offers no unique comments here. Additional comments are made in the Boston Airport ruins parking garage.

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 on the quest beyond temporarily interrupting Ingram's initial speech script when she runs to defend the scribes.
