GMST,
Good to see you active again buddy, long time no speak! I believe the Claxby was allowed whilst GDF was off for a significant length of time last time, but for some reason the goalposts have changed. I think they still have it available but it is the old "for information purposes ONLY". Must be annoying for the ATCOs and airlines alike as it impacts on service particularly in the VoY...get rid to the mil ASAP!
