3. Atmospheric gases are not sorted by molecular weight.Perhaps you should join the Cato Institute. You and Stephen Milloy would get on well.

SLAP!
It would appear that the designs i linked to are a smidge out of date. Here are some newer ones.

My favorite part:
Future archaeologists trying to understand what the Shuttle was for are going to have a mess on their hands. Why was such a powerful rocket used only to reach very low orbits, where air resistance and debris would limit the useful lifetime of a satellite to a few years? Why was there both a big cargo bay and a big crew compartment? What kind of missions would require people to assist in deploying a large payload? Why was the Shuttle intentionally crippled so that it could not land on autopilot? 1 Why go through all the trouble to give the Shuttle large wings if it has no jet engines and the glide characteristics of a brick? Why build such complex, adjustable main engines and then rely on the equivalent of two giant firecrackers to provide most of the takeoff thrust? Why use a glass thermal protection system, rather than a low-tech ablative shield? And having chosen such a fragile method of heat protection, why on earth mount the orbiter on the side of the rocket, where things will fall on it during launch?
