I see there is a workshop at the airport right next to the BOS ground base. Is it any good as a settlement? It as fare as I can tell has no place for food to be grown. And maybe one or two place to put in wells. Maybe right on the edge of the settlement. So what is this workshop for? IS this a place to set up a character base or can you make it work as a settlement?

Its part of a quest line, so its not really meant as a normal settlement. You can link it via a supply line and it will then have the resources to function.

Ah thank you I have not got that quest yet.

I built a base there so I'd have a place with no settlers (Piper's hanging out there).......I probably could have settlers though since I've several linked settlement producing food in bulk.

Interesting in or not, once you get the settlement it classes three locations, Boston Airport ruins, Boston Airport and the Prydwen as the same settlement giving you the same stats for all three.

U can't built a Radio Bacon there. (After Ending with Institute)

You can't build a beacon there at anytime.

You can however send settlers there from other settlements I believe.

Yeah you can send settlers, also certain companions count as settlers for instance Piper is currently the sole settler for my airport base.
