Thank you for the video link, Teeej; all good stuff.
And thanks to All for confirming the likelihood that they were indeed BUFFS passing over Cambridgeshire.
This all brings back fond memories of the RAF v SAC Double Top bombing competition days . . not sure if 1980 was the last Vulcans v BUFFs Double Top but I remember that the BUFFs didn’t do too well that year and hence on their planned departure day to the U.S. the BUFF crews were all made to “re-fly the bomb comp route” around the U.K. prior to then climbing out and flying back home to the States. Some form of “detention punishment” from their superiors to indicate their disappointment with the overall BUFF performance that year.
A little unfair I thought as of course there was always a little home team skullduggery in the RAF / SAC bomb comps hence we tended to win over here with Double Top and they always won over there in Barksdale with Giant Voice. Happy Days !
