Zeppelin makes Oklahoma City stop

The Farmers Airship, also known as the Eureka, travels at an altitude of 1,000 to 1,500 feet, and is capable of speeds up to 75 mph, but typically travels at 35 to 40 mph.

Unlike hydrogen-filled airships of the past, this zeppelin is filled with helium, a nonflammable, lighter-than-air gas. What separates a blimp from a zeppelin is the rigid frame inside the ship, which means that it holds most of its shape even when emptied of gas and the engines are mounted on the side and the rear of the ship, rather than the cabin.

“We like to say, ‘We don't fly. We float,'” said David Finney, guest services supervisor for Airship Ventures, the California company that owns the airship.

“The airship itself is a 246-foot long, 14,000-pound windsock,” Finney said.

“She works on the same principles of buoyancy as boats. Instead of floating on water, she floats on air,” he said.
