This story is quickly becoming more public. However i want to emphasize one thing. All this depends on exactly one scientific discovery and that is gravity manipulation. That was apparently understood in the mid fifties and was immediately kept secret. My associate's efforts have since confirmed the reality of gravity manipulation as well. I am not just relying on whistle blowers on their death bed.
My present conjectural framework suggests that our third tier matter merely provides a 'wave guide' for second tier matter which carries gravity as we know it. I also suspect that this second tier matter can be excluded using resonance and the ultraviolet. This is meant to be a hint for table top experiments.
This article is now firming up timelines and actual scope of operations including a very ambitious Mars program. I suspect we may be excluded from the moon.
We have 300 astronauts in 1985. We have Mars colonies or actually bases in 1995. This demands a major expansion. Thus we have Spacecraft fabrication beginning under the research umbrella of the space Race in the early sixties. Presume capability by late seventies. Understand NASA research advances since then along with Moore's law and all this works so long as we manipulate gravity and nothing else. Actual magnetic field propulsion demands material revolutions now happening but not possible twenty years ago. Thus our observed craft are still using jet engines in atmosphere at least. It also explains why we have such large craft. A gravity vessel can pack a million pounds of fuel if it had to.
All this remains Top Secret for the nonce. However it is becoming not much of a secret.
