Yes, yesterday afternoon, an airship flew over London, and many other British landmarks.
It has very good fuel economy, apparently:
The Spirit of Dubai is the world’s largest commercial airship and is managed by Airship Management Services, Inc (AMS). The Spirit of Dubai will operate at around 1,500 to 3,000 feet with a cruising speed of around 30 to 50 mph - the airship can reach speeds of up to 70 mph (or faster, with a tailwind!). While cruising at 30 knots The Spirit of Dubai airship consumes 8 gallons (48 lbs) of fuel per hour. During a week of operations The Spirit of Dubai will consume less fuel than a 767 uses to simply move away from its gate to a runway!
