I don't see the relevance of the final launches from either Ark Royal (IV) 27th november 1978 or from Ark Royal (V) December 2010, the important facts to remember are that FAA FJ pilots are training in CATOBAR ops with the USN NOW, and they will continue to do so leading up to QE's service entry. It's not about wil they or won't they, we already are, and the necessary bank of experience will be in place by the time it is needed.
