It makes sense, and was truly interesting, thanks Burimi..

Also the material used is now plexiglas with multiple layers which allow a stress reparation between the inner cabin and the outside. (note the for most of the planes outside windows are not the same material, for example boeing use laminate.)
Also you will find little holes at the bottom of a plane window which are used for pressurization equalization between the strates.
So the plane won't implode but regulate its pressure naturally in case of too high structural stress.

It always amazes me how no matter how complicate the topic someone in this community knows to enrich the video with an educated comment.

#2 The inner layer of an airplaine window does not bear any loads and serves no structural purposes. It is more an interior design feature, dust cover and provides some thermal insulation. Without the little hole on the bottom it would bulge inwards, or even pop out at altitude, what would be more than alarming for passengers.
Planes do not implode, if anything they would explode. But the pressure difference is not big enough to create an explosion. The problem is the formation of cracks in high-stress areas, which will at one point cause the plane to rip apart once a crack is long enough. If such a crack allows the air with wind speeds of 900 km/h - 4 times the speed of a cat. 5 hurricane - to attack, it simply rips of pieces and once the shape of the hull is damaged it becomes unstable and the wind can give it the rest.

There should be a way to delete comments, otherwise you end up with comments like this one ;)

#7 no way! I've commented under the wrong video and since I could only edit my post, I had to write some junk and seized the opportunity to complain about the lack of a delete function. :)

Why couldn't they make oval window frames but with square window in them, or some of those leaded glass windows then put a nice plant in a pot on a sill on the inside, so when you nod off and then wake up, you can think you are in your lounge rather than defying gravity in a metal tube with lots of people you don't know one of which might be a terrorist and a few others that might have Covid-19. 8-)
