I've read Vulcan 607, quite recently, and it explained to me in some clarity [very necessary in my case] as to why the bomb run was at the angle it was, the antiquated equipment, the bomb-racks recovered from a scrap yard. etc It also made it equally clear that one hit on the runway was all that was required, and the effect on the Argentinians was significant.
SASless, you really need to read the book, and if you can't get one I'll be pleased to loan you mine! It'll blow your hairback!
