Bugs

 * It's possible that when you are getting in the vertibird you stop at the Airport not at the Mass fusion OR, and when you go back to the Prydwen you can't enter at the vertibird anymore, reload at a save before leaving the inside of the Prydwen may fix the problem.
 * There is a bug when you jump off the vertibird to the rooftop. The quest does not advance and still tells you to jump off the vertibird.
 * It is also possible that when on the vertibird, the game will crash while trying to fight the synths on top of the first tower.
 * There is a bug when you try to board the vertibird but you get booted out, disabling the ability to interact with the vertibird. Reloading into an earlier save and making sure Procter Ingram joins you seems to fix it.
 * There is a bug wherein you are given the wrong tooltip key prompt for exiting the vertibird. (The right button was Q, please tell people what the right button is for future reference)
 * It's possible to have Ad Victoriam not be given after completing Spoils of War.
 * Fix: Reload the game to a point before you made the decision to either choose the institute or the BOS. Talk to elder Maxson to make sure you start the quest Outside the Wire and From Within if available. Step into the vertibird to start Spoils of War when these quests are completed.
 * Upon completion and back at the Boston Airport, Ingram may remain silent and can't be interacted with (despite the quest marker above her head), thus making the final step of the quest impossible to complete.
 * One possible fix is to reload a save prior to accepting the quest, and during dialogue, insist to go alone to Mass Fusion building. She will stay at the airport and can be talked to when the mission is complete.
