Roger that, I have heard some amazing stories about the cooperation between FACs and Callsign Magpie, really good team work and results. You should pick up the new Osprey book entitled 'B-57 Canberra Units of the Vietnam War' by T.E. Bell. Aside from telling the US story (a damn good read), there is a chapter on 2 Sqn and some really nice profile art for B-57s and B.20s.
