IT was as far back as December 2013, that you published a letter headed "Airport dinosaur." Since then every year has produced correspondence with headlines such as "Report on viability of Prestwick to be kept confidential" or "Airport flight of fancy is never going to take off."

It seems at long last the Government has had to bite the bullet and acknowledge that despite an investment of more than £40 million it is not possible for it to be commercially viable ("Airport is put up for sale as fears rise over £40m hit to public purse", The Herald, June 14). Indeed, a further tranche of £20m appears to be necessary to upgrade its facilities to promote interest and eventually a possible sale.

So much for its long fog-free runway and only recently the possibility of its nearness to Glasgow suggesting it only needed one more advertising push to secure traffic and its financial future. Even when or if the facilities are upgraded, who would wish to take a commercial decision bearing in mind its history? If that is the case what happens then?

No one can be pleased by this decision. That it has taken so long for the Transport Secretary to understand the economics of the situation is shameful. No doubt it was the fact that the SNP was reluctant, politically speaking, to be seen to be selling off the family silver, not realising that it was tarnished from the onset. There will be a coterie of engineering companies round the airport which will be affected. I have no doubt that their skills and expertise will allow them to survive. If only the Government had had the political will to take the necessary hard, unpopular decision at the time to reject it when it was offered for sale at £1, then Prestwick town might well have been able to get a makeover that would attract further inward investment.

It is easy to image that there will be a similar fudging over the ongoing dispute over the delay in the building of the ferries. It would not be surprising if that bill exceeded the one at the end of the M77.
