I believe that was the new starter, after they re-released the set with a consistent (and larger) vehicle scale. There has since been several releases for the various theaters, and WotC relased new revised unit stats on PDF as well.

Can an aircraft “see” through forests or hills and attack an enemy on the other side?
Terrain never blocks LOS to or from an Aircraft.
@Der:
Terrain never blocks LOS to or from an Aircraft.
So this means that anything in range of the aircraft can shoot back at it without LOS?
No.
Terrain doesn’t block LOS to/from an aircraft means only that. It doesn’t allow units to fire without LOS.
This is significant because Smoke Screen is not terrain and does block LOS to aircraft.
