nacnud - 19/2/2007 2:31 PMI agree, sort of. With that plan you are stuck only flying as much as the emmision regulators will allow. If you can find an alternative fuel then you could be free of such restriction and can sell to your competitors as well. The possible rewards are much larger, but of course so are the risks.
Saddly there is not a truely "green" energy source.

Well, considering that's what the C-17 was DESIGNED to do, no.Most of those average payloads were not that long.-snip-Back on topic. The AN-225 has a shoulder-mount wing, so a t/Space vehicle can be under slung, or it might slide out of a tube on top--and slide out the back, as long as the tube's top has an opening that gets wider the farther back it travels, so that the nosecone doesnt strike much.A 747 on stilts is asking for trouble.
Some points about the t/Space lauch system;A Scaled Composites Proteus performed a drop using a 23% - 24% CXV/booster mockup stack back in 2005. Proteus is nowhere near as powerful as White Knight, and given that the EVE is rumored to have the wingspan of a 757 but still be skinny as a rail its power to weight ratio must be something. Scaled was to build both the EVE for SS2 and the t/Space VLA. Many believe that Rutan isn't one to duplicate his efforts. I agree; he'd build one plane to the higher spec and make it adaptable like Proteus, which was the direct ancestor of both White Knight and EVE. Proteus had the option of 2 different engine types and could use wing extenders to go from 77' 7" to over 92' if need be, which is a very practical way to meet both needs.fd If nothing else Rutan is extremely practical.IMO no jumbo jets are necessary, just the EVE/VLA. Jumbos waste too much of their power lifting their own buns off the deck. Think how a Sky Crane is built vs. a Blackhawk or Mi-24 and which you'd rather lift a load with.
