Twelve thousand fett? TRUCK? Do you have a failure of imagination?
How about thirty five thousand feet?

I have been watching these lift bodies in the NASA Tech brief Magazine, and I like them. The one with the hypersonic ram jets that will burn best over 50,000 feet is innovative, and may allow a spacecraft the fly close to outer space before reaction mass is used. They think they can used a shaped outer hull with fuel injectors, that uses the supersonic air compression to provide the combustion air for the motor.
These pre rocket lift designs are a fuel saver for sure!
But if they take off from an elevated location (Denver would be Easy) will still save costs It is hard to compete with a simple truck for costs, even with a custom lift body. The only cheaper option would be a pipeline to pump the fuel uphill.
I had seen one concept using a Zepplin that was interesting too, it did not help much on launch speed, but it had altitude and hang time going for it.
