CZ and Sensible - the ac shots are from June 2000. The late afternoon/early evening of 7 June 2000, to be exact. I know that very well - because I flew as photo chase and took that photo of the 4-ship (over Hook Norton, British West Oxfordshire) and I also designed the paint scheme! It's 'flag blue' and 'solar gold' - the work was done by Mick Allan at Turwesty (and earlier at Spanhoe).
'twas the amateur radio photos from 1965 to which I was referring!
