MANY ex WWII aircrew served as ATCOS. It was my privilege to have worked with the following (that I can remember).
Fred Mann Hurricanes (during the BoB). ATCO at LATCC.
Ron Holton Lancasters (force landed in the Sahara at night whilst ferrying the Lanc out to India; took part in the 1000 bomber raids on Germany). Chief Officer ATC at Edinburgh.
Harry Dalton, ex SATCO at Jersey (flew Wellingtons).
There were many more, but my memory for names is bad. I'm sure many of my ex colleagues will expand the list !
