Very sorry to hear this sad news. I first knew Robin when he was an SAC assistant at Northern Radar in 1969. A great lad, with a wicked sense of humour.
Time passed, and roles reversed, and it was Robin who took me through my MER at Norwich in '82 when I converted from military to civil ATCO. Met him again in '95 when I went for an interview at Norwich. Still the same, irrepressible Robin.
A sad loss of one of ATC's characters. Condolences to all his family and colleagues.
