I did extensive research on that story including reading a 303 page book twice written by a former freeper who made it into a video which I also watched. If this was not a cia op than is was sanctioned or authorized by them. Had to be. Five different COD's(cause of death)? Endless stuff including some underwater photos that leave you at the very least wondering.
Not to mention the fact that they were barely offshore when the plane "crashed". that too is highly questionable more like a "landing" than a crash. I could go on but its basically endless right up to nttb using a fake engine for explanation of the crash and so much nonsense it's not even believable along with engine noise when the plane had landed!!LOL!
Being the personification of a C_A guy from conception, Barry has long reflexively given his urgent, politically-related ideas over to the Agency for fulfillment. In complementary fashion, people like his Agency Director, Brennan, would be at the ready to make sure the Barry narrative stayed the planned course.
...which is not to say that JOB and crew were particularly good at covering for the ephemeral Barry, without leaving clues. You point to one with CIA asset, "Loretta Fuddy's" five different causes of death (CsOD) The CsOD officially changed six times, serially. Indeed, it was well beyond strange. It was planned.
One reasonable view that coincidentally fits within the limitations of their trade-craft, is that these miscues are purposeful, to keep researchers, journalists and reviewers bickering about which of the Agency's lies might best represent the Truth. Honest exposure of the evidence would conveniently give rise to dis-information-spreading "debunkers" using the standard, obfuscatory playbook to lay down a smoke-screen attempting to paint a narrative that researchers "can't box their way out of the bag they're in."
