We know that Grusch holds the theory that NHI may be using some sort of dimensional travel. Personally, I believe he had to have seen something that led him to that conclusion. I dont believe he would have publicly made that claim without actually seeing evidence. But here’s what Grusch says at the hearing:
Democrat Rep. Jared Moskowitz of Florida asked David Grusch, a former Department of Defense task force member, about the existence of satellite imagery of UAP.
“I personally reviewed both what we call overhead collection and from other strategic and tactical platforms that I could not even explain prosaically. I have a degree in physics by the way,” testified Grusch, a former National Reconnaissance Office representative on the Defense Department’s Unidentified Anomalous Phenomena Task Force.
