The problem is that the alternative to closing DSA isn't a void. It's a potentially thriving industrial estate offering an attractive selection of warehousing and logistics opportunities adjacent to the M1 corridor. Interested parties will undoubtedly argue that this will support more jobs than the operational airport, run at a profit, and bring in significant income to the local area (and councils) without burdening the public purse. We can argue about the extent to which this would hold true, but it will be a compelling argument for change and we know that the airport in it's present form is an unsustainable loss-maker.
