- Yes, it's entirely plausible, although it might end up being somewhat
- larger than the shuttle for the same payload. NASA studied SSTO concepts
- early in the shuttle development, although the conclusion was "too
- much risk of performance shortfall".

- Gary Hudson claims that you could put six SSMEs on a shuttle external
- tank, without SRBs, and get it into orbit carrying a payload about 50%
- greater than the shuttle's. It wouldn't be reusable, though.
