I well recall amid my IR training in the late 60's doing GCA approaches at Manston. ATC would always accept such as a good method of training. Talk down was to 1/2 mile. I fine airfield with a fine history.
Many years later I did a real GCA approach at Goose Bay in blinding snow all the way to the ground. Then the 'Follow Me' found us and did a good job to get us to the stand.
