Asmodeus is not; he just links back to his website of compiled twaddle and blithers about "expert witness report analysts" as though the witness testimony was the ONLY evidence at hand. Any "expert" witnes report ananlyst can only evaluate the incompetent FBI agent's 302 reports not the actual witnesses' statements. The 302s are notes written by third parties unfamiliar with aircraft accident investigations FROM RECOLLECTIONS of what witnesses were ALLOWED to say in response to the incompetents' incompetent questions and often leading questions.
Many of the witnesses, when shown the 302 reports of their interview have flatly denied they said what the FBI says they did. Of course you will not find an "expert witness report analyst" who will agree with anything in the 302s... because they are NOT WITNESS REPORTS! No one ever properly questioned any of the witnesses as far as I can see. Some attempts were made years after the events.
