Later today the last scheduled Concorde flight is due to take off from London-Heathrow to New York-JFK, returning tomorrow. There's a good article about it in last week's Economist titled "the less beautiful future of international business travel" and I agree. Too expensive? Sure, completely out of my bugdet (and most of the planet's too :)). But so what? Concorde is a fascinating piece of engineering and its beautifully designed. Sometimes I find it good to know that certain things exist. They provide a yardstick: "Here's what we're doing now, you go further". We seem to be losing a lot of those these days. [d2r]
