This is further recounted in [this video], although the illustration is crude and possibly harms any credibility: I like how Ashton puts forward his case in the Kim Iversen video, and also how he discredits the discreditors. I have seen these "CGI experts" put forward a case against other such things; because CGI is their thing it, it is through this lens that they are able to provide their perspective, that pretty much anything and everything can be recreated with CGI. Just because it can, doesn't mean it was, or even, with the case of modern-day movie effects (which is their other forte), should.

My only contribution here is to point out that it is not a wholly unique case; Hastings book shows how nuclear testing and launch sites were visited and interfered with during the cold war, and with this link along I propose that there was some nuclear or other weapons/technological purpose behind the disappearance of MH370. To just disappear a commercial airline out of sheer folly seems nonsensical.

The question remains, as it did at the end of Hastings' book (and the cold war period it was largely basted on), are these craft the creation of some "secret government tech" or otherworldly? It could even be some otherworldly tech in the hands of a secret government...

A case for the former comes from another incident I read of that has become somewhat of a conspiratorial legend (and I thought of when watching the clips of MH370 supposedly vanishing):

The Eldridge, which as Wikipedia states was a destroyer escort ship of the US Navy, launched in 1943 and decommissioned in 1946. As part of its service it was fitted with degaussing coils used to help protect it against mines and/or make it invisible to enemy radar. This was part of Project Rainbow, aka The Philadelphia Experiment, mentioned also in the book [Sands of Time by Sean David Morton*]. This lead to the so-called conspiracy that expands on the ship being "invisible to mines/radar" to it having the ability to be "optically invisible". Furthermore, when the system was activated for the first time specifically on August 12th 1943, and so the story goes, the vessel shifted out of phase, causing crew to be stuck in bulkheads and killed. Horrifying stuff. A part of the official details that appears odd to me, is that the ship was only in service for three years - perhaps this was normal for a craft of this period in time, but I can't help but imagine that if the ship did succeed in travelling back in time some years (and/or suffered damage due to such an experiment) then it would technically have reached its date of decommissioning sooner. The ship was sold on however, which makes one then wonder what happened to the panels with bodies stuck in them... You can read more about the experiment [here].

Back when my original iteration of my website, BMH Online, was in its infancy I had a section titled UFOs, because I was, and have been since, intrigued by the topic of UFOs. But I've had little to add to the subject; I have little in the way of first-hand eye-witness accounts, only an armchair perspective. Here are the two examples I presented on my website in 2001:

A frame grab from my webcam that I proposed could be depicting a UFO,
but mostly like is just a bird!

I'd visited an online weather forecasting website
to find this trail across the sky. I don't know how to explain this.

Since you've read this as part of my Advent Calendar, there have been suggestions that very Nativity story, with the star in the east and the three wise men, is one of extraterrestrial basis. Indeed, the gods of the bible could like wise being alien beings.
