The quote from Page 22 of the European rule book appears to be open to multiple, contradictory interpretations.
I agree that, clearly, a carrier move to the plane’s SZ, in place in that SZ, or could be mobilized in the at SZ is needed that COULD recover a plane. The rule does not specify that the carrier MUST recover the plane. Moreover, my interpretation of the last sentence (“You can�t deliberately move an air unit out of range of a potential safe landing space”) means you cannot move the plane BEYOND the range of a carrier’s move, where a carrier will not be, or where a carrier cannot be built. A plane can be moved to SZ where there is a POTENTIAL safe landing spot (not a guaranteed safe landing space).
I suspect the moderators need to rule on this one.
