Actually Grimweasel if you had an ounce of intelligence you'd realise that the Vulcan trip was merely a warning to the Argies that their precious homeland was within range of our strategic bombing force. The attack on the airfield had to be made from high level at night and as the clockwork bombing computer was designed to deliver a single nuke within 50 yds or so of it's target I think it did admirably well to stradle the runway with a stick of unguided bombs.
Oh I see 'nearly there' beat me to it by a minute!
