Karl Nell is a retired U.S. Army colonel with a background in national-security space programs who has publicly stated he corroborates elements of David Grusch‘s allegations regarding a secret government program involved in recovering non-human craft, as referenced in the David Grusch Testimony.

Assessment

Like Grusch’s own claims, Nell’s corroborating statements remain unverified by any released physical evidence, and AARO‘s AARO Historical Record Report (Volume I) did not find evidence supporting the broader retrieval-program claims either man has described.
