I wanted to clear up some misinformation that folks have been confidently passing around in the comments on this sub, claiming that David Grusch only interviewed 4th hand and 5th hand (!) whistleblowers who just read reports and stories from other people. This is false, some of Grusch's whistleblowers were firsthand witnesses who were in the facilities and have touched recovered craft:
From Grusch’s congressional testimony [1]:
>Mr. GRUSCH. I know the exact locations and those locations were provided to the Inspector General and some of which to the intelligence committees. I actually had the people with the firsthand knowledge provide a protected disclosure to the Inspector General
From an interview he just did with Judicial Watch [2]:
>Grusch: the evidentiary threshold was high and the people I brought to ICIG, you know, were hands-on, they touched it, they were in the facilities, um, and they, you know, they were well cleared people, and they weren't misconstruing a recovered adversarial aircraft for something else [or] some of that gaslighting that's been going on which I find honestly amusing
