Volare!

Volare! is a side quest in Fallout: New Vegas.

Detailed walkthrough
Volare! is the final quest to complete for the Boomers, and the first one they receive upon entering Nellis. The Courier needs to help the Boomers around Nellis enough to become Idolized by them. This can be achieved by completing quests for them and by interacting with certain Boomers.

Quests that grant Boomer reputation:

Boomers with special interactions:
 * Argyll needs help with his patients.
 * Pete at the museum has a story to tell, which is worth listening to.
 * The Boomer teacher's curriculum can be improved.

After becoming idolized, report back to Pearl in her barracks. She recommends asking Loyal about the Boomer's dream of flight, and he gladly tells a story about the submerged bomber and how he wants it to be raised from the bottom of Lake Mead. To achieve this, he hands out two deployable ballast devices, as well as his detonator.

Before heading to the Lake Mead, Jack can optionally be asked for a rebreather to allow for underwater breathing. To obtain it from him, passing a Science check (45) or bringing him a pressure cooker is necessary.

Travel to the map marker to find the crashed B-29, near Callville Bay. Quickly dive under and attach the ballasts between the two engines and underneath the wings, on each side of the bomber. A hollow 3D image marks the exact spot where to place the devices.

Once both of the ballasts are attached, travel to Callville Bay, where Loyal's detonator will start to beep, indicating that the Courier is in the correct position. All that is left to do is to equip Loyal's detonator as a weapon and fire it to raise the plane.

Travel back to Nellis and speak with Loyal (he has an optional Intelligence check of 7, with no impact on the outcome). Then talk to Pearl to complete the quest, which grants experience, a Boomer outfit and further raises reputation with the Boomers.

Behind the scenes

 * Volare! was outlined by Joshua Sawyer and later fully implemented by Akil Hooper.
 * The crashed B-29 is based on a real world crash site, referencing a Boeing B-29 crashing into Lake Mead on July 21, 1948 - the same date in-game and in real life.

Bugs

 * Sometimes after completing the quest, the bomber in the hangar will not be repaired. It will look the same as if the Courier did not start the quest. For a fix on PC, see the Nellis hangars bugs section.
 * Sometimes when starting the history lesson at the museum in Nellis, Pete will begin talking about the Boomers, then when he finishes his first part of the speech, he wont move and will stand still. The bug seems to be triggered by activating Pete's other dialogue options. To avoid it, select only the second dialogue option (the one that activates the story).
 * Othe possible fixes include pushing him as short distance by walking into him, sleeping in a bed for a couple of hours, leaving and re-entering the building, or loading a previous savegame.
 * Sometimes Loyal will not be in the hangar after this quest, which effectively stalls Raul Tejada's side quest, since it requires to speak with Loyal.
 * Sometimes the quest is activated after the first conversation with Pearl, regardless of reputation with the Boomers or Karma.
 * It is possible to enter Nellis at the gate by entering a conversation with a NPC in the middle of an active artillery barrage. However, after doing so, the barrage may continue when one is leaving Nellis later on.
 * If choosing to kill Pearl and Loyal while Jack isn't present, there is a chance that he will not be hostile. He will behave as though the Courier helped to raise the B-29 bomber and can still be given scrap metal. If Young Hearts has not been started, the dialogue to initiate the quest will still be available, even though the Courier will immediately fail the quest due to killing Pearl.
