Mark,
Don't forget the 2 airways established to widen AMBER ONE in the late '60s/early 70s.
AMBER ONE WEST,,,,,,,,,,,Whitegate - Stafford - Honiley.
AMBER ONE EAST............Pole Hill - Lichfield East - Daventry.
Can anyone scan any Aerad or similar charts to the web from the inception of 'airways' to the 1970s?
