Two points arise from this discussion.
First NOTAMS aren't hard, a narrow route brief and a phone call will tell you all you need from NATS and there are numerous reasonably reliable graphics sites if you need them. There is no excuse, if an old f@rt like me can cope so can anybody else.
Second what in heaven's name are our authorities doing setting up temporary controlled airspace for Americans, let alone permitting them to take some sort of official role in an airport control tower on British soil? Have we gone completely nuts?
