I've decided to post this topic on here, instead of the Fallout 4 forum, to avoid it being buried in 5 minutes.
Anyhow, so I thought everyone would be bashing Bethesda for the pre-war vertibird, but people are strangely silent about it. That makes me think that I've yet again missed something in Fallout 2 and am wrong about vertibirds being an Enclave invention. So, since there's not much info on this topic anywhere, can someone tell me where vertibirds actually originate from? Or is the one in the trailer not actually the same type of vertibird?
