@94Canuck:
Ran into this one last night. I looked through both Europe and Pacific books in regard to Neutrals. Can fighters/tacs fly over a strict neutral during NCM. Examples was UK Pacific fighters flying up to help defend Russia. They can make it in the alloted moves in 1 turn if you can, if not it would take 2.
Actually, no aircraft can ever fly over any territory while it is neutral, including not only strict neutrals but pro-Axis or pro-Allied neutrals.
Note that you could, however, take control of a strict or unfriendly neutral in combat, and then fly over in non-combat movement in that same turn.
