At Rimmer Airport News we've got the the full spec (have had for quite a while now) basically LOX (London OXford) is a proposal from a consortium led by Hoctief Airport (Don't mention Shoenfeld...OK I will but only if the price is right). Never Mind Brize it makes an impressive bo££@x of LHR airspace...
But having been missed out of SERAS (into which it would have fallen) basically it's pretty much dead in the water (or resevoir) of course that could all change at any time up to the white paper published.
