Sorry if this has already been brought up before, and if it has, can you guys link to the forum post about it? Thanks. Anyway, the Vertibirds in Fallout 4. They shouldn't exist. At all. First of all, Vertibirds run on gasoline, of which there is none. Zilch. Zip. The last preserve of gasoline was destroyed by The Chosen One after all. It's stated as much by the Enclave that that was the last bit of petroleum. Now I can KINDA understand there being vertibirds in Fallout 3. Considering they're supposed to be the same Enclave from Fallout 2, just migrated to the East, I would certainly imagine they brought a few barrels of gasoline with them before fleeing the coop. In New Vegas we only see 2 Vertibirds, one of which owned by the President of the NCR himself. Now I can't really explain this Vertibird's existence because, unlike the Enclave who probably brought oil with them in FO3, the NCR shouldn't really have any access to gasoline. I'll just make the assumption, since it's really the only one we see outside of the Enclave Remnant's, they have just enough gasoline to power it. Perhaps it runs on mostly ethanol gas (corn fumes)? Meanwhile in Fallout 4, not only did the Brotherhood somehow manage to get ahold of Vertibird building schematics (I'll just assume they got it from that one Vertibird you fly out of at the end of Broken Steel), but they have tons of these things! They're everywhere. All the time I'll hear the sound of vertibirds puttering across the sky only to inevitably be blown up by a stray bullet because those ships have 1 health. Hell, you even get your own vertibird in the game, even though it's literally just slow fast travel, aka completely useless. There aren't any flying enemies to shoot or any sort of danger while you're in it. So how the fuck do they have this many Vertibirds? They sure as hell don't have the gas for it. I can't say they got it from the Enclave bases because they blew up both of the Enclave bases (Raven Rock and that weird mobile base thing from BS) Is it ever explained in the game? I never went through the BOS storyline because after playing it through with the Railroad and trying to play it through with the Institute, I just gave up. I could understand maybe 1 or 2 Vertibirds but an infinite number of them without any gas?!
