If you feel the urge to ask me what those hypothesis are - then I think you'll see the point.
I think this is part of my point because it's obvious why: he crashed the plane on purpose in an extremely dry area, so he took a fire extinguisher with him in hopes of extinguishing any fire he started. He concealed it because he was faking the crash. He's also an idiot there as well because it took him a while to get to the crash site, which was much too long for a mini fire extinguisher to be useful.
So see? It's obvious and not interesting. He's just an idiot.
Granted, what the other commenter pointed out is indeed an interesting facet, which is to your original point as well, but it's more to do with engines and planes being interesting.

If people find the other threads we can add them to the list here.
It definitely made me look at online debates a lot differently, as previously I thought good points can come from anywhere (which can still happen), but it turns out experience in the domain is usually way more relevant.
I guess it's similar to that effect where if you see news about a topic you don't know, you tend to take/believe everything as-is, but if you happen to know the domain, you'll usually spot quite a few factual errors which tend to discredit most of the news.
My expertise is education. Everyone has opinions about that field. Many, many, many are just completely ignorant.
It's why I try not to weigh in too heavily on areas that I have no practical experience in.
