Nice... That would be a great conversation starter at home... feel free to reach out if you put the idea in motion!

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.

Sounds do-able. Radio available on the web too. https://www.liveatc.net/

Another cool way to do this would be an ADS-B receiver on your roof. They're about $30-40, and when paired with a Raspberry Pi, a waterproof box, and free software[0] they work really well. Plus, you get a free subscription to a lot of flight tracking services like FR24.
