There has been very little support for the Airport by the local authority and council, it's my personal opinion that their determined objection to the new terminal at Coventry was the final nail in the coffin.
Regardess of covenants, scripts written on parchments or whatever it may say in the Midlands Bill of Rights, I can't see Coventry reopening as a going concern.
It requires someone with £millions to clear the debts alone, but, as an airport that consistently proves it will never have enough commercial traffic to cover anything like the running costs due to continued opposition from local authorities, no one in their right mind is going to take it on.
I dare say that the local authorities who own the lease and the site will ensure that everyone who has any interest in the place will be "persuaded" to go elsewhere and that by this time next year it will be a business park.
