I remember two met men at RAF Bovingdon in the early sixties. One was very short of hair and had a lump on top of his head. We called him Cu Nim Charlie and he was very optimistic in his forecasts. The other was a miserable type who tried to put us off flying anywhere in our old Ansons. If you managed to talk to both forecasters and took a line down the middle of there predictions you got a reasonably accurate forecast.
