In my humble opinion, the most interesting/novel thing about this project is the approach to solving the classic "the code is coming from your server every time I open Airborn OS, so why should I trust it" problem. Basically, I'm using Service Workers to install a small piece of code which from that point on checks that all code matches the version on GitHub [0]. There's a blog post with more info here [1].
