Projection Tech

3D Volumetric Projection Technology from the 1960's

I've noticed something strange... The UFO / UAP community are backtracking and now talking about "holograms".
A better description is 3D Volumetric Technology.
Remember "Project Blue Beam"?

What if it's already been used?
Are you able to admit that to yourself, if you were presented with evidence proving it?
Or will you be one of those people that goes into a COVID coma, denying the evidence?
