This is an easily accessible area with a handful of bloatflies and radroaches. Enter the building and cross the broken walkway to reach the control room. There’s a red trunk there and an issue of Tumblers Today. After exiting the building, you may be ambushed by a couple of mirelurk hunters.

In the hill between West Everett Estates and Poseiden Energy Turbine 18-F, there’s a crashed bomber and a couple of tanks. You’ll find an incomplete Power armor set here.
