Taking a couple of steps back from the detail (although I have been a user of Coventry on several occasions in the last few years and would like to see it continue), I invite you to contemplate the following:
1. In the past there were lots of local authority-owned airfields. Most of them didn't make any money but that didn't seem to worry the ratepayers.
2. Now, running airports is largely the preserve of multinational corporations with massive credit provided by multinational banks.
3. Privately-owned airports have difficulty making a profit.
4. Local authorities have been progressively starved of cash.
5. Multinational banks have received billions in taxpayers money
Feel free to draw your own conclusions.
