The sad thing is that alpha may not be far off the mark.
However, instead of us getting F-16's, the USAF or RAF would probably just be allowed to patrol our airspace and maybe use Shannon (or Dublin) airport.
I have read that the GOC pushed for the PC-9's because they have HUD etc., and will allow AC pilots to train to 'jet standards' - which has a lot of merit.
Basically, it's as close they can get to flying jets, without actually flying jets !
As for Turkey's Bord Failte idea, it's a good one.
However, I reckon that when the PC-9's have 'settled in' we will see a new AC display team formed using 4 x PC-9's.
