Obsessed. That’s what Russ Magnuson and his small group of volunteers are when it comes to the Goodyear ZNPK-28 Blimp Control Car at the New England Air Museum. His crew has logged 21 years and close to 24,000 hours to date working on the rare airship. And they still are not done! This is the only WWII configured K28 blimp car in the world.
