Having been subject to many threatening lawyers letters from Ryanair, I am sure Danny (Captain PPRuNe) could lend all the libelled Irish ATC staff some examples which they could use as templates
Of course, in every case the threats to PPRuNe have come to nothing, because the truth isn't libel
Unfortunately the crap spouters from Ryanair probably would have difficulty recognising what the word 'truth' means.
