Not bad. :-)
Still, there would be a lot of anachronisms if the setting was as written. It's doable (a "future" USA of 40 or 50 years ago), but I don't know how well it would actually work.
Maybe it could be Taggart Hover Craft, and Rearden Polymers could create the lighter than air fusilage.
I actually like the odd futures created in films like "The Matrix" and "Dark City", where older style is combined with futuristic technology. Personally, I'd like to see it as a period piece with an "alternate history" feel to it, just so they can have fun with the industrial design and the architecture. I liked what Tim Burton did with Gotham City in his Batman movies, kind of a German Expressionist style that goes back to the days of "Metropolis". It fits with Rand's storytelling, as well.
