For example that hydroplaning is a real consequence on runways; or that higher takeoff weight has an order of magnitude greater effect on runway wear than the shear force of braking during landing.

I also learn from Grady's phenomenal skill at communicating technical concepts from our field in layman accessible terms! Most times I prefer to watch his videos and appreciate what he does, but there are days that I'm in the mood to read rather than watch. I'm glad that he gives us that option.

If you don't then I'm sure it's better than nothing but idk if stock footage is where you should be developing your mental model of how a tire hydroplanes or how a paved transfers load into what's below it.
