First and only time I saw this gentleman in the flesh was at a PFA rally at Wroughton almost two decades ago, when he was top billing on the display, advertised as the Gary Numan Harvard Racing Team, or something like that.
Two things I remember from that day are that I saw him sitting in the pilots briefing tent with all the seats around him empty with everyone else (including his own team members) being seated some distance from him, giving the impression he was being avoided and that when the air race commenced, his Harvard led the formation for one circuit prior to the start of the race proper, only to peel off and land as the remaining Harvards went on to race.
I often wonder if this was planned or he'd pulled out after going "tech" and as no announcement was made as to the latter being the cause, I had to draw my own conclusions.
I am left with a lasting image of an individual sitting alone and looking very forlorn!
