Mod Design Questions Fallout 4

[Moonjelly3]

Myself and a few associates are working on a mod for Fallout 4. It involves a hot air balloon. One that is able to carry the Player into a new world space (A vault in Roanoak NC). Any tips or pointers where I should start working on making this work. I have a little creation kit knowledge and am currently learning. Thanks.

Have a look at how the game devs did the trip to Far Harbor. :) (boat, instead of ballon.)
