   Repo: https://github.com/davidmegginson/ourairports-data
   License: Unlicense (Public Domain dedication).
   Notes: OurAirports data is generated daily. The primary CSV used for airport lookups is
          `airports.csv`, which includes columns such as ident, gps_code, name, municipality,
          iso_country, and iata_code.
   Required attribution: None required (public domain), but attribution is appreciated.
   Recommended citation: “Contains data from OurAirports (ourairports.com).”

2) OpenFlights (ODbL 1.0)

   Data: https://github.com/jpatokal/openflights/tree/master/data
   License: Open Database License (ODbL) v1.0 (https://opendatacommons.org/licenses/odbl/1.0/).
           Any rights in individual contents of the database are licensed under the
           Database Contents License (DbCL) v1.0.
   Files used: airlines.dat (airline ICAO/IATA/name/callsign/country/active),
               planes.dat   (aircraft ICAO/IATA/name).
   Share-alike note: If you publicly share a modified/derived **database** based on OpenFlights,
                     you must distribute that database under ODbL 1.0 and keep OpenFlights attribution.
                     (This obligation applies to the data, not to your application’s source code.)

Practical guidance
------------------
• Airports: Prefer OurAirports for airport → city/name mappings (public domain).
• Airlines & Aircraft types: Use OpenFlights (ODbL) for ICAO → human name mappings.
• If you publish your merged/pruned JSONs, include:
    - This THIRD-PARTY-NOTICES.txt
    - The full text of the ODbL 1.0 (recommended as LICENSE-ODbL-1.0.txt)
    - A short note in your README acknowledging both sources.
