Eureka Airship
Often seen cruising Bay Area skies about 1,000 feet off the ground, the Eureka airship is one of only two of its type in the world, and the only one in the United States that carries commercial passengers. This German-made zeppelin, owned by Airship Ventures, is not a blimp; though both types of airships are filled with helium, only a zeppelin has an internal framework.
