I believe that the aviation fuel tanks have been replaced with fresh water storage tanks, so future ops are unlikely. The fact of the matter is that operating offshore is bloody restrictive because of the limitations in roll and pitch allowed for take off and landing, so all the NS saw was a bunch of pilots and techs land in Cork harbour, retire below until they were required, get quite sick in some cases and not be able to fly again because of the swell. Most pilots were only too happy to push the limits of what was possible just to get a respite from the motion, in fact, I know of one pilot who could only eat in the aircraft, nothing would stay down otherwise. Now you tell me why it appeared that they were always so eager to get off the damn thing!
I've seen some pics of an IAC Alouette on 'a deck', but I'll have to see if the guy in question will give me a copy. The lack of a harpoon or negative pitch facility makes for an interesting time, I'm sure!
