We've only ever had one terrorist attack in our airspace, The Air India B747 in the 80's. And the aircraft didn't go through an Irish Airport...
Besides I went through Munich INTL, yesterday, now they have security checks, I don't think Dublin INTL even turn on there metal detecters half of the time (I wore the same amount of metal going throught DUB on the way over as in Munich, and guess which side I was stopped at, not to blame the staff; only the IAA!), and as for proper baggage scanning! Baldonnel is nearly up to the job as much as Dublin, even without investment!
(I still like the idea of Weston, and besides noise problems!)
The Debate Will Continue!
