Also from BBCnews, this article detailing the discovery of a 1500 year old boat in "Langstone Harbour", wherever that is (I've notice this a lot about Britain, that they never actually tell you where, exactly, a spot in their country is. Probably a Whig conspiracy...)

Oh, the Arthur reference? King Arthur, if he lived at all (probably did), probably was around some time between 470 A.D. and 520 A.D., maybe as far out as 560.
