This is really a piss contest.. If NHT is not safe, then Bizet shall stop flying all at once to Africa, China, South America, Russia, etc.... and even some airfields in USofA ...
Have a break, have a KitKat... As long as there is no scheduled movement and "public" traffic in and out a MILITARY base, they can rule whatever they like. Operators have just have to make the numbers to work.
All too much politics and bureaucrats behind this, just let the planes to take off and land like they are doing it for what ? how long NHT and the 125 ? Cannot remember, late 80's I landed there ( I was based in Hatfield, another massacre from aviation idiots), so please, let our airports open, and let these firms to study a sixth runway in LHR...Or to stick with ICAO phraseology... How about that ?
