As it suggests in the interview, if that is CGI from '91 it's very impressive, literally incredible according to experts. The other possibility is a model, but as always the lighting and quality of footage makes it difficult to see clearly. If half his claims about the corroborating evidence surrounding this video are true the argument for this being real is compelling. It can't be easily dismissed, it's creepy as hell, but I can see how this could be safely dismissed as a hoax by most people. Perhaps that's one reason why it's on YouTube and the personnel in the video have been trusted to keep their secrets for many years.
I found it interesting how John Stewart summarised the findings of the government studying 'grays' for decades - they are "some sort of half synthetic robot and biological being with tissues". Very close to 'cybergenetic probes'. He claims that the new government program designation will be 'SABER' - standing for 'synthetic astro biological extra terrestrial races'. We'll have to look out for that. Otherwise he correctly predicts a soft, limited disclosure resulting from the congress hearings. He doesn't seem to have much understanding of the extent of disinformation, anything suggesting this is hyperdimensional in nature, or the complexity of the situation regarding the military and various levels of secret government.
