This thread inspired me to pull out the display and finally tinker with it - and then I realized how expensive the APIs are for this data - especially if trying to do a "constant updating" style approach like you'd want for this idea.

It makes sense you listen for the sound of a plane / wait for a button press before making the call!

Seems like this would be best done with a receiver and monitoring that directly and/or exchanging the radio logging for API access.
