GCA's
Mike
At Honington we had a very long in the tooth air trafficer who had been a founding father of GCA in the UK. As I'm sure you remember, the controller's patter was an integral part of the system much as is a QFI's
Our venerable controller was from the Forest of Dean with the lovely rounded vowels of that area.
He was sent to Denmark to train his Danish counterparts in the system and for years at many a Danish airfield you could hear a Dane saying, " You are sitting noicely ahn the gloidpath, ahn the senterloine. Adjust yore deescent to the correct rate for yore toipe ahv errcraft."
Pity ILS came in really
