The Argentinian fleet air arm (just because im tired and cannot be bothered to spell) keeps its pilots and deck crews experienced by flying off US navy aircraft carriers whenever they are near Argentina and by having deck crews working on US navy carriers and Brazillian carriers as well as postings with the French navy. We have far closer ties to the french and US Navy so I cant see why the Royal Navy cant train personel even when we dont have carriers yet.
Our needs and ways of operating will of course be different to the French and Americans in detail, but the boys and girls learning how to make things work will no doubt get the training they need and then will build from there. Steep learning curve for sure but they arent starting completely from scratch.
All this naysaying about not being able to have trained crews is just dull. We have people already learning how to operate with the US Navy and the numbers will only increase in the run up to the carriers coming into comission.
