Enemy Air Vessels:
• Will not move using Ferry Routes or Graticules.
• Can move through the center Sea Region, counting it as one Region, but MAY NOT stop there.
• May not stop in any Sea Region; Its final movement must be over land. (Rotate its direction clockwise until the compass is pointing at a Land Region and go there instead.)
• End movement immediately if entering a Region you control, which results in a Battle.
