He’s Buster Keaton.
I need to rewatch it all again now that I know where it goes. It feels slightly confused at times about what it’s about. Is it about aviation safety or about Nathan’s anxieties about whether there’s something wrong with him? Is aviation safety ultimately just a perfect metaphor for the question of whether there’s something wrong with him (very inspired to find an industry that fully embraces simulations to set this in) and all of the talk about actually improving aviation safety is just a feint (despite all of the doubling down and swearing that he actually, sincerely means this literally)?
At the end, is he withdrawing back into himself, and lying to himself, because the validation provided by being a pilot is irresistible?
Anyway, yes, brilliant stuff.
