Skipness one echo
I'm very much inclined to agree with you that Ryanair will not stay to any meaningful extent at Prestwick, of course it would be politically explosive to say so now so close to the referendum and they need to get a Summer program on sale. I don't think the outcome will influence what Ryanair do one way or another, but the recent launch of their enhanced business package shows which way they are thinking, one only has to look at Gerona & El Prat.
I hope PIK can find a business solution I have many fond memories of HMS Gannet, BAe Cygnet, Bill MacCloud, watching Concorde doing touch and goes and more recently Monarch circuit bashing.
