You can also leave the building and walk towards the lake (where you were dropped off) and you'll be asked in you want to return to DC. That's the way I always left the Kenley college area. And I'm also aware of long pressing the "G" button to return to DC cause that's the method use to leave the Pentagon map area.
The gunship will attack and leave the area until you get to the area where you have download the Black Tusk Data. The way I defeated the the gunship was to take cover under the platform on the left of the map. From there targeting the big red radar or camera under the middle of the gunship will take it out quickly. A powerful rifle will do massive damage.
Oh, and it helps to clear the foot soldiers first so it's just you and the gunship. Or if you're good enough you could take out the gunship first than clear the foot soldiers.
