Hmmm questions, questions, BDIONU:
NAS is the most modern FDP system in Europe, having been recently completely rewritten.
So, if it has been
completely rewritten there will be no lines of 1960s vintage 9020D in it
at all? True or false?
I also note no one has yet answered the question:
why would the world's best system need to be shut down once a week?
NOTHING has been done to sort this PROBLEM out. Why not? Why are we still stuck with the WORST DD&C option? Perhaps because the Operational Staff are still coping with the aftermath of a crap management decision years before...... I have yet to see ANY NATS manager admit they made mistakes here... I HAVE seen at least one still trying to justify his demonstrable errors.
BTW has anyone EVER seen a NATS manager being suspended and offered re-training (community service)? No, thought not.
