Thanks all - I suppose it makes sense to research your target in advance and learn the entry and egress routes, although I assume the comment about "Buccaneers targeting SA-2 sites" was with conventional weapons, not tactical nukes ?
As an eager spotty teenager I remember getting a map of Europe and placing pins in all the RAF bases and then tracing radius of action arcs for each type of aircraft. It was surprising how little penetration into "enemy" territory there was for anything that wasn't a Vulcan. Especially the much hyped 200 foot low level attacks which burned off so much fuel.
Of course it never occurred to me that some of those missions may have been planned and briefed as one-way only.........
