I wonder how many times Christopher Mellon has been convinced of UFOs in the past.
Something I've noticed with this recent dump of videos is the only people I personally know who are interested in convincing themselves that it is truly unexplainable are ones who have already claimed other videos represented UFOs as well. A lot of people have taken the "I want to believe" mantra to heart, and it has affected their ability to actually reason about what they are seeing.
Visual and radar confirmations of what, though? A balloon is a physical object that you can see in visible and radio light.
The data seem to show a slow-moving object at a higher altitude. I'd trust the actual data over nebulous claims of an object appearing to be moving fast. It's hard and unreliable to judge an object by eye, and easy to fall prey to optical illusions.
The debunker doesn't address the fact that in addition to the FLIR-lock, there was multiple visual and radar confirmations.
