- Well, up until now, people haven't been claiming "TSTO will be cheaper
- than SSTO." They've been saying, if we have a few large payloads that
- can't be broken down, TSTO will be cheaper than a larger SSTO because
- it's cheaper to develop [an unproven assumption]. However, liquid
- propellents certainly don't constitute a large payload that's hard
- to break down into smaller pieces.
