Campaigners took their opposition to Stansted expansion to the courts today, but are there other reasons to think it might never happen?
Another day, another airport expansion. It's a bit like the opening to Hitchhiker's Guide to the Galaxy - as Arthur Dent lies in front of the bulldozers to protect his house from being flattened to make way for a road, the man from the construction company berates him: "What do you mean, why's it got to be built?" he says. "It's a bypass. You've got to build bypasses." Substitute runway for bypass, and comedy morphs into reality.
