I am not a pilot, but I find the whole idea of flight magnificent. I have an understanding of the mathematics behind it, but it still amazes me every time I see a plane take to the sky. Looking at some aircraft, I find myself wondering how that can obey physics, but they do... and they fly.

I also find the intricacies and quirks of the industry itself intriguing. Not so much fairs and budgeting, but why things are named the way they are, how rules and policies evolve, etc.
