OAP, surely a civil airport has better security? At an airfield near me there were holes in the wire and the runway ends are practically open. Back in the day Prestwich offered secure parking.
There does appear to be a lot more overt security around the perimeter of Newquay Cornwall Airport, including very tall f*** off fencing, than in the days when the same establishment went under the name of RAF St. Mawgan and had US Marines loitering around the bomb dump menacingly.
I appreciate the key word is 'overt', but even so...
