@Baron:
Talking OOB rules, all planes on a carrier can roll for defense including any friendly one carried on board. So, if a fully loaded 2 hits carrier is hit and damaged by Subs only, both planes must land elsewhere after combat.
I think that the point which Larrie was trying to make was that a damaged carrier should not be able to launch any planes which are still on the carrier, or recover any planes which are already in the air.
The “if a fully loaded 2 hits carrier is hit and damaged by Subs only, both planes must land elsewhere after combat” situation described here combines two contradictory situations: the planes being on the carrier and the planes being in the air.
If the carrier is “fully loaded”, this means that its planes are on the carrier, not in the air. Therefore, the part which says “both planes must land elsewhere after combat” doesn’t apply because, in order to “land”, a plane has to get into the air or has to already be in the air. A damaged carrier should not be able to launch planes, so the planes in this situation shouldn’t be able to get into the air.
If on the other hand the planes are in a position to “land after combat”, it means that they’re already in the air…in which case it’s not correct to say that the carrier is “fully loaded”.
It’s either one situation or the other, not both at the same time.
