- Depends on *who* goes up on it; sensible people will look at the reliability
- figures and conclude that man-rating decreases the chances of a successful
- flight (because it runs up the cost without increasing reliability).
-
- The astronaut community is less conservative, overall, than their official
- public image would have you think. You'd have plenty of volunteers from
- there if the engineering looked sensible and the purposes looked worthwhile,
- even disregarding the number of qualified volunteers from elsewhere.
-
- However, Doug's point is nevertheless valid, because the original context
- was official government projects... and it is official NASA dogma that
- man-rating is mandatory for such purposes.
