Yes, as Beagle says, SWB used to work for the NATS NRB. I recall others e.g. BZ (Brize NDB?).
I still want to know who Squadron Leader Hooton is...
Never take the micky out of this one. It is a vitally important notam
But, yeah, he must get an awful lot of phone calls............
If you want more amusement, do an NRB for say EGKK-LTBH and read the reams of Greek v. Turkish airspace disputes, referencing agreements done in 1952 or whatever...
The problem is that it is now so easy for interested parties to create notams, that everybody throws in everything including the kitchen sink.
