Another try: Make a site that shows when airplanes are going to be close to your position, and include a dead reckoning-based forecasting functionality that lets you set an alert when any of currently detected planes are going to be passing by in the next ~30 seconds. HC option: Do this with an SDR connected to the Pi, instead of using adb API's.
