and what did BB cost in terms of its use of assets and the risk to those assets and their crews?
i'm not one who dismisses BB's results, because as political - and political impacting on the military - results they were very considerable, but BB did not close the airport, and the resources needed to close the airport through the medium of BB were not just phenomenal, but not available. had the Vulcans/Victors been equipped with LGB's and Martel then perhaps a very different picture would emerge, but as it stands, SSN and TLAM is both far less risky and cheaper...
there's a tangent: if instead of carrying 21x 1000lb bombs BB had been carrying say 4x 2000lb LGB's what proportion of the IFR's BB used would they not have required? enough to allow two Vulcans to get down there?
