Is the airport data live?

No. It comes from a pinned OurAirports snapshot imported into the ToolsOnDuty data layer.

Where does the airport data come from?

The snapshot comes from the OurAirports downloadable airports.csv dataset on GitHub. OurAirports releases this data to the Public Domain, and each result includes the pinned source version.
