Get the vertibird plans for the Brotherhood of Steel

Walkthrough
If you go to the Brotherhood of Steel outpost (located at the South-West of San Francisco), you'll meet Matt, the only member in town. If you ask about the Brotherhood of Steel, Matt will speak about their history and a recent meeting with The Enclave, who have developed Vertibird technology. The Brotherhood are interested in acquiring the Enclave's Vertibird plans, but have been unsuccessful in obtaining them. Accept the quest and Matt will give the location of Navarro, an Enclave base hidden within a gas station North-West of San Francisco.

Accessing the base
Matt will advise you to go there alone to deceive the Poseidon Gas Station attendant, Chris, into believing you're a new recruit, a decent speech level is helpful, start the conversation with 'Ever heard of the Enclave', if successful, it will produce a series of one line answers which convinces him you are a 'newbie'. Alternatively, if all your NPCs are wearing Power Armor, Chris will not suspect them. After deceiving Chris, he will give you the password "Sheephead", allowing you to safely enter Navarro (located behind the Gas Station, crossing the forest). Give the password to the Enclave Guard at the entrance. The player may also simply kill Chris, then go down the ladder in his shack; the people inside will assume you are a member of the Enclave. You can tell them you're a new recruit to access the armory, containing a few notable weapons, ammo and a set of Enclave power armor. If you are not wearing Power Armor, the Enclave members will advise you to go to the armory and equip some lest you are reprimanded by the Commander.

Getting the plans
Many Enclave technicians will point you to the location of the Vertibird plans, including Quincy, a maintenance technician at the north-east hangar with a truck, he will inform you that you need autorization. To get this, go to the vertibird hangar to the west and speak to Raul, he will tell you how busy he is. At this point return to Quincy, and inform him that Raul needs the plans, he will then tell you that they are in the locker behind him (the one on the right).

Return to San Francisco and talk with Matt; he'll congratulate you and will make a *copy* of the blue prints and give them back to you. This is convenient, as there are other parties interested in obtaining the plans. Matt will then grant you access to all the Brotherhood of Steel bases and their equipment.
