It's outrageous that these secrets are still bloody secret eh!!!
I heard about the Roswell crash years ago when I was a teen and but brushed it aside thinking it's all crap, but last year I took the time to watch every video relating to it!! And Fucking Hell!!
It led me on a massive trail exploring S4 base, Tr3b's Element 1-15, dulce base, The Petro Dollar!!
( Bastards... Has to stop!)
I really enjoyed David Adairs description of an Alien engine he was shown deep in the depths of the S4 base.
I will link it. A fascinating story in itself. I really don't think he's bullshitting!.

I have tons more to tell as well man.
Since discovering all of this I have had a few experiences!!
Will reveal more if asked :)
Cheers Thomas.
