I won't name the other poster but to suggest closing such a long lasting site and move it close to a site where nobody has heard of.
Not the only one to come up with such a daft and risible plan, Boris was pushing for the establishment of an airport in the Thames estuary ("Boris Island") and the closure of Heathrow.
That scheme never took off and is now never mentioned. Boris is now the MP for Uxbridge, a town near Heathrow. Could it be because he now has many constituents who work on the airport? Or is that too cynical?
Both "Boris Island" and Church Fenton have one important thing in common, they are both notoriously bad business propositions. Consequently, in a country where civil airports are privately owned, neither is going to fly.
