That is exactly why I think is only a camera effect.even if we put a box around our eyes (like blinders on a horse) to restrict the view, i think our brains would override and visual that might be there ie. our brain knows we are moving. add: and where we are in space "spatial awareness"
And even (I know this is subjective) when I watch this video repeatedly on the big screen, I can see what Mendel was referring to that camera shake is quite evident once the type of effect caused here is known. Simply the zoom and the lack of visual references camouflage this movement very well.
Personally, if I had to bet, I'd say this guy purposely shoots these videos to make them look like "anti-gravity planes", but it's a bit puzzling what his motivations would be; Unlike other types of scammers, it doesn't seem to make any financial profit. It could be that he's doing it for entertainment, but man, it's a bunch of videos on his channel, like he really believes in his own BS.
