Oh wihipping one
It might not seem it but I'm more or less in agreement with you with regards shared usage of airspace. We obviously differ as to the viability of P18 but it is fairly inevitable as we are looking at it from the opposite viewpoints.
As for RAS, well, it all gets back to corporate liability. Should the unthinkable happen it would be NATS and the ATCO involved in the dock. The rules stated we should provide separation and we didn't. Big fine for NATS, prison for the controller? Suddenly it becomes even more of a risky game.
Sorry to drift quite a long way off topic...
