- Do you suppose that DC will not belly-up from time to time, too?
- The only space boosters which never failed were Saturn 1 and
- Saturn 5, and neither flew 25 missions. Who's to say that the
- firm which operates DC would not be ruined by an ill-timed DC
- wreck? Grounding Shuttle would be a political decision. Grounding
- DC would be a financial decision. The end result is the same.
-
- If the development costs are as high as you claim, the costs of
- such Shuttle upgrades as the new turbopumps and the glass cockpit
- are marginal. Even the ASRM is a drop in the bucket next to those
- numbers... Seems you're using two different figures here, a low figure
- which makes the upgrades a major increase in the costs and a high
- figure which makes Shuttle an impossible-to-recoup investment.
- Which is correct?
