Building a LofiATC alternative and need some input from others

I'm working on an app that will take the place of lofiatc.com since it no longer works. Just trying to get a feel for how others think you should interact with it.

I'd like to make it easy to discover airports. I've been playing around with tables, grids of "airport cards", even manually typing ICAO codes, nothing really feels right. I'm open to ideas. Still in the early stages at the moment so there's not much pressure in finding the perfect solution right now.

Also, I'm going to open source the project once it's in a more "steady" state. If you're interested in the project keep an eye out on github.com/Bitlatte
