Navpi, you're clutching at straws now.
The owners of Heathrow have paid millions already towards a project that was approved years ago. This is down to governmental incompetence and political meddling. It costs huge amounts just to plan a project like this and the lifespan of the construction could run over multiple elected governments.
It is right that they should seek compensation should the whole thing suddenly be cancelled or sabotaged for political means. This is not just so HAL can pocket the cash, it's more about being able to pay suppliers and stop those suppliers and contractors going to the wall.
