A free mod for Fallout 4, by registrator2000.
This is a F4SE plugin that lets you jump from Vertibirds.
The idea is that you can find a way to land to the bottom of the tower, and from there you can get to the next floor.
The way to do this is to find a way to get to the top of the tower, which is not going to be an easy task!
You can also jump from a vertibird while in flight.
The reason for this is that the game will let you equip a weapon, and if you are in flight you can use this weapon to shoot the target.
