Dick,
What you say re surveillance of Approaches is doable. Most problems in the world are doable if you throw the resources, committment and money at them.
My concern is that you try to intimate to people on this forum that it is a simple matter of flicking a few switches, writing procedures and away you go.
LHRT comes back after a telephone conversation with you telling us how simple it is and wouldn't cost anything. It will cost a fair bit in either extra controllers or bringing Flight Service back to life.
