(Editor) Need help with making a unit lift off and fly away

So here is my problem: I am trying to make a colony ship lift off after a trigger. I got it to actually use the ability, but I do not know how to make the unit itself move to a point and de-spawn. I cannot seem to find help anywhere so I thought I should ask here.

Go take a look at the WoL mission “The Evacuation” in the editor (which I believe is called THanson01), especially the victory cinematic.
