It's quite clear that long-enduring heavy lift designs such as Atlas, Soyuz, Delta and Arianne have been the best investments in space hardware over the last half-century.
They're the Fords of the rocket world. maybe not as romantic as the Ferraris and Maseratis of experimental craft like the Space Shulltle, but a damn sight cheaper, less temperamental, and less time in hangar...
