An update on the Freugh:
Qinetiq currently run the site on behalf of the MoD. Luce Bay Range (D403/402) is used regularly by both air and ground assets and proves a very useful facility.
Sadly, the runway is now closed with big white X's painted on it although it is still in remarkably good repair. In the last few years the airfield has seen quite a lot of helicopter traffic and some C130s but run as a greenfield site.
