Kuragary, you're partly correct. In AC5 (I don't think ACZ had it), you could land in some places after taking control of them, but that was up to the game and it was a post-mission minigame. However, in AC6, you could help allies that are trying to take the airport and then, once they've captured it, land whenever you want during the mission to rearm.

That last part is what I definitely want to see more of, in Infinity or future games. :D
