"Jeff Findley" :

If we're talking about the same flight profile (carrier aircraft lifts
hybrid powered spacecraft which is dropped and ascends to 100 km), what
would need to be different, aside from scaling the design up by a factor of
two?

Call me dumb if you want as I am no R.B. but I think/feel that some changes
in the carrier craft will be needed to carry a heavier craft. Most aircraft
design can not be simply scaled up without changing something. A large craft
will need more powerful engines or more of them for example. More engines
means changes ofcourse, more powerful engines probably will not find an exact
scaled up match so some changes there.

Besides it still is R.B., why scale up when he can design a newer better
machine to blow our minds I don't know how he does it, my best guess we
live on Earth, He lives in a world of flight and hydrodymanics.
