ATC Airways & Frequency details, early 1970's
I am researching into the following UK airways of the early 1970's.
Can anyone give me the details of the following airways, where they started and finished and also the frequencies under their control if possible....
AMBER ONE
BLUE ONE
RED THREE
AMBER 25
I think they still exist but there 'start and finish' points may now be different.
Any help would be greatly appreciated.
