I know the discussion settled long ago, but since @apollyon was last to post something that seems incorrect, I think it better to rectify.
The Pacific 1940 2nd Ed. rules clearly say p31 “If that carrier is destroyed or damaged in combat, they [the defending fighters] must try to land on a different friendly carrier in the same sea zone, move 1 space to a friendly carrier or territory, or be destroyed.”
I cannot find the exact quote in the rules, [please bear with me], but you spend one move each time you cross a dividing line on the map :
- from a territory to another territory, (land and air units)
- from a sea zone to another sea zone, (naval and air units)
- from a sea zone to an island/adjacent territory and vice-versa (air units)
Since I don’t have Europe or Global, let me provide an AAP40E2 example:
A FIG in SZ36 having defended from an attack on their previously undamaged but now sunken CV could land on :
- another friendly CV in SZ36 (no move), or adjacent SZs 20, 35, 37, 43 (move 1 space),
- FIC, Kwangsi or Hainan island if any under friendly control (move 1 space).
They could NOT land on any of friendly Formosa, Philippines or Borneo (move 2 spaces), nor on Malaya, Shan State, Siam, Kwangtung or Kiangsi (also move 2 spaces).
