Thanks for the quick reply. I think the rules should be errated as follows:
Page 14 under Strategic Bombing, 2nd paragraph,2nd sentence should read. Escort fighters can escort and protect the bombers and they can originate from any territory and carrier.
Also, Page 12 under Air Units 2nd para, last sentence should read:
Fighters or tactical bombers can move their full four spaces to attack in a sea zone instead of saving movement, but only if carriers with sufficient basing capacity for all attacking planes could be there for them to land on by the conclusion of the Mobilization phase.
I my game Japan wants to attack the US feet in the Line Islands on j2 with 15 fighters and TB but can get only 1 carrier there to land on. So only 2 can move there and attack.
