For discussion.

The UFO research has been fuzzied with all kinds of misinformation by the agencies, by some people who were psychotic or channeling, and by people who like to fool people.

For discussion. I do think that Corso is not correct and may be spreading some misinformation.
"Day after Rosswell" goes mainly about how the UFO phenomenon became beyond top secret.

The transistor is a gradual step after the tube, the science is very similar even when it looks different.
The technology was already in development in WW2, starting with Germanium.

The laser seems magical, and the science around it seems lacking.
But the technology is pretty simple. You just need a crystal, a mirror and a semi-transparent mirror.

I think that the real science that is hidden can be found by how the science community attacks certain topics, even when there is good evidence.
Here is my list:

1) Low-Energy-Nuclear-Reactions, which has been replicated in the labs multiple times. Some ray-emitting technology might have been related with this.

2) Huge errors in all of Einstein's theories.
Einstein's theories work most of the time (in certain experiments), but not all the time.

3) Living bodies have an aura and a spirit. The aura can be measured a bit, and seems to cause some changes in electrical processes or faint light-emission.
But there are also other physical properties that can change. For most people it is easy to change the physical properties of a plan, via attention. Famous is the Iceman who can swim in ice-sea water, but there are several chi-masters who can focus energy to create heat or cause chemical or nuclear reactions.
