Aliens and Demons: Evidence of an Unseen Realm

[Ninurta]

I haven't watched it yet. I wonder if it mentions the story about the first night vision googles used in the Vietnam war were the people that used them were freaking out because they were seeing demons and creatures through them and the military discontinued their use.

I heard about that too, they used dicyanin dye in the lenses to filter out certain light spectrums.  I can't say either way to it's veracity, but it's very interesting.

At one time, and maybe still, you could get glasses with the glass containing dicyanin dye. Folks said you could see "things" through them. I never tried them, so I'll never know, I reckon.
