- The *redesign* (yet again) of Freedom required for it to be launched
- by Energia would very likely cost more than any launch cost savings
- that might be achieved. Planning Freedom from the start for launch
- on a heavy lifter would have been the cheap way to go, but at the time
- of Freedom's initial design the Russians were the "Evil Empire" and
- we didn't have any heavy lift in the class of Energia operational.

- A SSTO *might* be a low cost launcher, or it might not, but a VHLV it
- is very likely *not* going to be. SSTO claims of low cost depend on
- reusability. The only reusable launcher we have experience with most
- definitely *isn't* cheap. That's one of the things *research* vehicles
- may tell us. That's why I support them. I'm not going to gamble taxpayer
- money on another operational system until it's costs are *proved* to be
- enough less than current vehicles to make it's deployment cost effective.
