One of the new Zeppelin firms is right beside the Friedrichshafen airport, and part (all?) of their business is scenic flights. There's certainly a frisson watching a zeppelin rise into the winter sunshine with the Swiss Alps behind it; made the RyanAir flight I was waiting for seem more than usually tame.

Tame, but also quick, cheap, and safe. I'm glad I'm not an investor in such a firm, but also quietly glad that others are.
