I admire your enthusiasm and persistence but I think you should also know when to quit.
You've thrown a proposition out there for debate and that's your right and privilege. Fair enough.
But you've been trounced in that debate and now you should gracefully withdraw.
Summary points:
1. There are already too many airports in the North of England
2. The business case for another one cannot be made.
3. All the arguments about a Yorkshire International were previously made in respect of Finningley. The relative failure of that venture will, in itself, be enough evidence to scare off all potential investors in CF whether they are private or public.
4. LBA isn't going to just disappear.
5. If it was 'forced' to close, the owners would demand and receive very substantial compensation for their loss. The government would not be paying this, nor the Yorkshire LAs, nor a private company. So who would?
6. There is nothing stopping SAS or AF or LH serving LBA - or Yorkshire right now - nothing. They don't. Why would the existence of a so called 'proper' airport change that?
7. The Vale of York is a well known 'fog spot' in any case.
8. You are railing (with some justification) about decisions that were taken decades ago and in economic terms are practically irreversible.
9. Cost of associated infrastructure: airfield upgrade, terminal construction, new link roads, rail link (?) would run into hundreds of millions. There are better opportunities to spend the nation's wealth and better opportunities for the reduced number of private airport developers and operators too. This will never be an investment priority.
