No they didn't!
I flew the VC10K with the press party (AP, ITV, BBC, TASS, AvWeek, Flight etc.) on that trip; one problem was that the F3 outfit had an extra jet which they positioned between the VC10K and the MiG 29s, which was an infernal nuisance. After we met them over the North Sea, all went fine until the descent through the Daventry sector, when ATC weren't very helpful. We had to leave the formation and rejoin below cloud, by which time the F3s were doing their own thing contrary to the brief.
But the journos got their shots for rhe magazines and the video went out on the evening news!
