Two questions:
1. What is the difference, in this context, between a CV and an airfield? Are you willing to make the same argument for undestroyable ack for airfields too? If not, why not? Airfields can't even change course. So surely that would be the next argument. Its the thin end of an unappealing wedge.
2. Why are threads like this showing up in the General Forum lately instead of the Wishlist Forum?
