The point being that a certain amount of woe and hysteria was being conjoured up for what is in fact a perfectly routine occurrence.
It may be a perfectly routine occurrence offshore but only those airfields not in CAS onshore will have an unprotected instrument approach. It is an issue, especially when the airfield doesn't have radar.
The MAP for Gloucester takes you to the edge of the ATZ but then climbs you and turns you back to the NDB hold at 2800' - ie outside the ATZ in class G (normal hold is at 4000') . You are possibly IMC with no radar service where anyone can just fly through.
