I think if the Spanish authorities are genuinely concerned about safety, they should address the woeful inadequacies of their own ATC system first. It's the worst in Europe.
They won't of course, because the whole thing is politically driven.
I don't like agreeing with MOL (it brings me out in a rash) but on this occasion I think he makes some fair points.
That doesn't detract from RYR's own in-house problems which, really, are a separate issue.
