Oh, not illegal. One advantage of being the government is that you get to
make the rules. But government contractors who worked their books the
way NASA does have been barred from doing government work and some
executives have been jailed.

There is also the issue of dumping launch services. We enact all sorts of
sanctions against others who dump.

There are also a number of sections of various commercial space laws
which is at best pushing it and at worst violating the law.

NASA is chartered as a research organization, not an operational agency.
Shuttle is operations, not research.

Or provide insurance. Of course, if we add say 3% to the development cost
we can fly three times as many flights as Shuttle needed to be declared
operational.

That is a problem. Shuttle has shown that a government can dump launch
services quite a bit. But I assume since US launch dumping doesn't bother
you that this wouldn't either.

The US market, if fairly awarded, is big enough.

However, DCX is on budget and has slipped very little (30 days in a three
year contract). It looks like these guys know more than you about how
do schedule launcher development.

I'll accept that. It appears that the system, which you have spent so much
effort defending, simply doesn't work very well.

Amazing how low costs are possible for Shuttle but not for DC. It would
seem to me that this paragraph argues very well for a very low cost DC.

Which is indeed half the battle. But since you back Shuttle no matter what
it costs, I don't see your point.

Yes but *WHY* did Shuttle fail? Mostly it failed because of the system
under which it was built. If that doesn't change, then space will NEVER
be cheap. DC works under a different system.
