Early Spaceflight Designs

Interestingly enough, the Solomani Sourcebook for Classic Traveller has about a page or so about the activities of UNSCA and the development of jump drive. In a bit of serendipity, the premise presented was that jump drive DID serve as an in-system form of travel for several years before becoming adapted to interstellar flight. Much of this material gets re-presented in G:T Interstellar Wars, along with some new material.
Another thread in this disparate weave is the idea presented elsewhere about a Traveller universe with no Ancients, which would result in a cautiously growing Terran Confederation, eventually having to deal with the Aslan, Hivers, etc. Not sure if that idea got developed further, but it's not exactly the direction I was planning to follow.
Hmmm!

There's a similar thread to this one in the Imperial Research Station forum, having to do with reaction drives (from a T20 perspective).

OB: most of the materials there are from a dubious source... and are going very pro-trek...
I wouldn't call that similar...
