      • was made of 16 inch thick blast resistant steel plate
      • had gasket seals against radiation and biological agents
      • was shielded against rfi (radio frequency interference) and emp (electro magnetic pulse)
      • could be operated manually or monitored and operated pneumatically from the equipment readiness center
  • V012: Looking back at the emergency exit (and entrance) door.
  • V013: The structure in the center is the mezzanine (see section below).
