Yes, if the JCA requirement does eventually follow through with one aircraft type, then I agree about it being jointly manned (a highly logical argument). But if the navy went F18s for a few years, my point is that I would imagine they would be manned exclusively by the navy, while the air force find their own solution to the capability gap (probably more typhoons). I was speaking to a guy that's just left the MoD, who said talk of this as an alternative plan is rife, with a view to re-visiting the F35 in 10 years time... as demonstrated by the commander in chief fleet's comments.
