The reality is that PIK doesn't make money. There may be many training flights and military flights but they do not make enough money to cover the operating costs.
When the government took over they retained the management team "for continuity". The only problem is that they continued to operate as they had been - very badly.
The reason the airport was taken over by the government is that it was badly managed. Tom Wilson has now left, but the remainder of the management team continue to fiddle while Rome burns.
The Scottish Government has some blame to carry in this, they have spent, from what I hear, over £200,000 on a report and this has yet to be released, along with a credible plan for developing the airport. Meanwhile new business opportunities come, had tours of the facilities and then disappear again - never to be heard of again.
It seems the management are comfortable getting ad hoc rent for the Polar Hangar from BA for a couple of months in the year rather than have sustainable businesses move in there.
There is a place in the Scottish aviation landscape for PIK but it needs management that can recognise it and have the imagination to build the business, but not by selling one of the runways or holding car boot sales.
