Skydiver, asking questions like that is only going to lead to despair and thoughts of what could have been...it's best just not to think about it. Just know this, by the time they are both finished, they are likely to have cost us around £4 billion each - or more - which means they now both seem destined to end up being more expensive than the USS George Bush...which is nuclear...and armoured...and has a far bigger air wing capacity...and has 4 catapults...and is fast...and has a very good defensive suite, but it's all okay because it's secured the long term future of an uncompetitive shipyard in Glasgow
