Exactly! That is why one of the stongest proposals for a "new" heavy lift vehicle is to mount the main engines to the bottom of the ET and put the payload on the top of the ET. What's funny is that even with larger SRBs and 4 main engines instead of three the "new" vehicle still falls about 20 metric tonnes short of the Saturn V Low Eath Orbit capability.

I can't really argue the reusable vs. non-reusable case for launch vehicles. However, you should distinguish between critiquing the design of the space shuttle and critiquing the choice to build a space shuttle. You are really saying we should never have built a space shuttle at all, which is really a political rather than an engineering decision, but couching it in terms of a design critique.

Burtakus, I think its naïve for you to think that------ââ¬Åchina shuttle is old technologyââ¬Â. In the next few years china will become the center of technological achievement (how much depends on America).if we American donââ¬â¢t start looking @china with a serious approach. on your next vacation pay a visit to shanghai.----see for yourself----their skyscraper and finance district will reveal new York and Chicago.

If we Americans stop being naive about Chinas potential and technology ---we will be in trouble -----made in chine does not equivocate, cheap and low tech anymore. The Chinese have both the money and will to out pace American----the question is? Due we American understand this? I hope that NASA cleans itself up and continues to be successful? And I hope to never watch these pictures on TV!

china has a good gig going right now. They stole they protected and they were not pushed because we figured better industrialized and friedly.
But let us see how they do 20 years from now.
Notice Japan ran into problems.
We have problems so of them because of our meat head educators.
China will have problems too. Let us see how they deal with a society that revolts against the dictatorship.

I wouldn't bank on it.
Historical examples galore showing 'advanced' slave civilizations lasting hundreds, sometimes a thousand years.
Heeeyyy Burt, you need to get a life and shave your eye brows and maybe you would be able to see the truth. I think they should just strap an ACME rocket to the top of an 18-wheeler and send it into orbit. I mean, that sounds about like what your suggesting. Do you even work with a company affiliated with any space program or do you just sit around and watch the discovery channel all day long. I have heard better assesments of where the NASA Shuttle program should go from my older brother. So do us all a favor and leave your ignorant, ill advised suggestions to yourself and leave the thinking to the grown ups. Need I say more? 
And if you feel like further debating the topic, give me a call. I'm pretty sure you know my number.
