- Sorry for the misunderstanding. No, I suspect 10 flights a year is possible.
- I doubt 12 can be done without MAJOR changes.
-
- But given the very poor record of Shuttle performance to schedule, I assert
- the burden of proof is on you to show 12 can be done. I'll accept any two
- consecutive calendar years with 24 launches.

-
- A DC is simple and reliable enough that 50 flights a year is reasonable
- with the specified ground crew. At 10 flights a year a DC ground crew
- has lots of idle time so not only are more launches possible, they
- will also work to lower costs. Increasing utilization by 25% should
- be no problem (if DC works).
-
- With Shuttle, 10 flights a year utilized everything pretty much 100%.
- Adding more flights under these conditions means that costs must go up.

- Nobody puts people into space just for the hell of it. They are there to
- perform tasks. Given that, one can ask what those tasks are and wonder
- if there are cheaper ways to do those tasks. We can also decide if the
- tasks are worth doing at the price we must pay.
-
- I assert that there are no payloads which must fly on Shuttle and are
- worth flying. If you are going to disagree, please do so with a cost
- analysis or your arguement will be meaningless.
-
- Don't you see the damage you are doing to manned space here? Manned space
- is seen as a boondogle and nothing more than a jobs program for aerospace.
- Your astatements that Shuttle must fly regardless of cost only reenforces
- that view. You are making it easier for our opponents to harm us.

-
- There isn't a payload in existance today which can't go up on either.
-
- As to being more powerful, only if you are spending somebody else's
- money.

-
- This is bogus. By this arguement nothing new should ever be built. If
- you have specific complaints about DC, state them. The arguement 'well
- all projects have problems therefore DC will have problems and therefore
- it won't work' is bullshit.

-
- More of the same; I'll bet you $50 that it starts flying regularly. Well?
