The Discovery show "Contact", Episode 2 "Declassified Breakthrough" (aired Aug 14 2019) focuses on the Chilean Navy's "UFO" case which was completely and conclusively solved in January 2017. The object was identified without a shadow of a doubt as being Iberian flight 6830. And yet they present it as an unsolved case, seemingly pretending they don't know what it is, and that the temperature (the IR glare from the engines) and the trail (a contrail, black like the clouds, because contrails are clouds) are mysterious. Here are three shots from yesterday's show:
The idea that "there were no flights in the area at that time" is 100% verifiably false. It stems from the initial misunderstanding of the helicopter pilots, who though the object was much closer than it actually was. It was actually a plane departing from Santiago airport, far to the north of where the crew thought it was.
The reason they present this long debunked case as having any merit seems to be that the title of the episode is "Declassified Breakthrough" and the big deal is that they are getting access to files from CEFAA.
CEFAA is the organization that spent two years trying to figure out what the video shows. They failed, then released the video declaring it a "confirmed unidentified". The next day I posted that it looked like a plane leaving an aerodynamic contrail, a day later we had candidate planes, and within a week it was conclusively solved. The discussion thread is here:
And I wrote about the process here:
Getting the files of an organization that failed so miserably with their flagship case would not have been such a compelling episode. So they had to make it look like the case actually was still unsolved, and the CEFAA was the real deal. It's not. If they got something like this so very wrong, a case with all the evidence easily available, then it seems unlikely they did any better with cases where far less information is available.
