Re: Windows XP will not be used ... when the ship becomes operational,”
No -one has preserved a flying Harrier apart from the US Marines afaik. Given what it has cost to preserve the Vulcan thus far, a Harrier might well cost even more, plus the difficulty of finding any qualified and recently experienced pilots to fly one, and getting a UK permit to fly given the complexity of the aircraft. (See also BAC Lightning, Concorde and so on).
