Possible Space for Facility
- Watervliet Facility The circular spaces for the testbed were generated by Ken Connor but they agree with Kevin Smith's more accurate diagrams.
- Additional Floorplans for Wvlt Facility Provided by Kevin Smith of CP&FD. A possible circular space for the testbed is shown in a few rooms. Updated Floorplans (Earlier plans showed a pillar where one did not exist.)
- Watervliet Address: 805 25th Street (Most convenient entrance at the back, near the loading dock. Building is secure so access is only possible by contacting occupants.)
