On "Media Sources" --- this is one person's opinion, which is based upon decades of UFO work, and therefore is full of historical bias --- therefore you must take it with salt (as it is "conservative" despite the writer being utterly convinced of UFO reality):
A. UFOs have been so mocked and "forbidden" for so long, that highly trained researchers have been driven into largely private not-public non-exposed lives. Thus ALL the really good researchers are mostly unknown. Since they know so much, they know what is terrible bunk along with what is astonishingly true. They realize that there are almost no questions about UFOs that have simple and simple-minded answers --- all real answers are complex, deep, and "long." This is the group of people that you want to find if you're lucky.
B. There are many opportunities in modern media to make livings in the business of selling startling UFO claims. It does not matter to the media whether these claims are true or not, just that they are startling. These opportunities for the clever have attracted persons who don't really care what is correct. This applies to both the claimants and the commentators heading these "documentaries." IF a "commentator" decides to really go for it and make this gig his/her source of income, then there is pressure to keep delivering whether there is any truth to deliver or not. They become quite happy to accept and present crap with a wink, take the cash, and go onto the next piece of garbage. These are the people, for the most part, that you, the public, actively now see displaying themselves on TV and internet sites. If you are unlucky, you get fooled by their schtick.
C. So who is "A" and who is "B"?
Remembering that "A's" are more conservative yet take more work reading and are less cheap thrill in nature, the best scientific organizations working in the US are the SCU of Robert Powell (Scientific Committee on Unidentified Aerial Phenomena) who have a couple of web presences, plus annual conventions, and recently had two pieces on NewsNation interviews (Rich Hoffman and Robert Powell.) The second top quality organization is, unfortunately, in the process of refurbishing it's website --- The Center for UFO Studies (CUFOS.) This is the group originally founded by Dr. J. Allen Hynek. Anything you read there is essentially gold.
Close to SCU and CUFOS in responsibility is the NICAP website run by Fran Ridge. Fran is a lifetime field researcher who has also been bombarding Congress and AARO with documented UFO information, as has Jan Aldrich, who has sent copies of my book (UFOs and Government) to basically every interested congressperson and office. Of all the Pop media people there are two that I would basically trust: Journalist Leslie Kean and blogster Ben Hanson. I don't know Mr. Hanson, but my listening to him has shown a sensible person. Both have been part of the media coverages lately, and Leslie for two decades. For responsible notices of on-time news, read the news columns on the ANOMALIST website. These are collected and annotated by a good friend and top quality mind, Bill Murphy.
"B's"? Some of your favorites are "B's". This includes George Knapp. He MIGHT be accurate occasionally, but he has made a living for four decades pumping out stories like clockwork, and not necessarily well researched. This goes back to his Art Bell and Robert Bigelow days, when both persons in their different ways required him to produce excitement on the clock. The female twin of this was Linda Moulton Howe who became even less discriminating. When I look at Ross Coulhart I get similar shallow research and put it out there vibes; same with Corbell. Nick Pope is a complete sell-out clown --- note his regular howler appearances on Ancient Aliens, where he has negotiated a regular paycheck. His UK UFO desk assignment was a basement-level joke by the way, where he doesn't seem to have even known the extent of the earlier UK files. ... a government incompetent who however has the savvy to exploit his old title. I and my buddies also think that Lue Elizondo started OK but is heading down the Nick Pope path now that he's exhausted what he actually knows. Newbies like Tom Delonge might be a wide-eyed hoper as far as I know, but he rarely knows what he's talking about. MAYBE he gets some truth once in a while, but at base he is a naive sponge.
As I said --- my "feelings" not yours --- but these comments would be nearly 100% agreed to by the forty top UFO North American researchers all of whom I know well. ..... we could all be wrong.
p.s. anyone who is quick to want to take credit for things is both immature, self-aggrandizing, and not my guy.
