I bookmark this page and load it whenever something starts circling/passing overhead:

Regular plane noise is a regular thing where I live - I'm right under one of the regular flight-paths for a nearby very busy airport and very close to another busy airport.
One idea I've had for a while is to take my eInk raspberry-pi accessory and poll this data and have a constantly updating "what's overhead" display.
