This latest leak of OA info is worrying - but not because there is anything new or particularly worrying contained - but because the way it is being spun and presented is quite dangerous.
At the end of the day both B and C are pretty capable, but there is a risk that the "we can't afford cats/C" and "B is no good" soundbites may end up giving the current loonies the excuse they need to buy neither!
Those knocking the B now are playing with fire - and may leave the UK with nothing and selling the carriers.
