I have seen those, and I am a bit confused. If these are supposed to be IATA codes there are several problems: KCK: according to https://en.wikipedia.org/wiki/Kirensk_Airport and https://www.iata.org/en/publications/directories/code-search/?airport.search=KCK this is Kirensk, Russia MFW: according to https://en.wikipedia.org/wiki/List_of_airports_by_IATA_airport_code%3A_M and https://www.iata.org/en/publications/directories/code-search/?airport.search=MFW this is Magaruque Island, Mozambique although http://www.gcmap.com/airport/MFW says it is closed. NRW: according to https://www.iata.org/en/publications/directories/code-search/?airport.search=NRW this does not exist. But according to https://iata.codes/airline/polizeifliegerstaffel-nordrhein-westfalen-nrw-hummel-de there is 3-letter ICAO (not IATA) code NRW for "Polizeifliegerstaffel Nordrhein-Westfalen", aka a police helicopter squad. QDV: according to https://en.wikipedia.org/wiki/Jundia%C3%AD_Airport and https://www.iata.org/en/publications/directories/code-search/?airport.search=QDV this is Comte. Rolim Adolfo Amaro, Jundiai, Brazil QSF: according to https://en.wikipedia.org/wiki/Ain_Arnat_Airport and https://www.iata.org/en/publications/directories/code-search/?airport.search=QSF this is Ain Arnat (also "8 May 1945"), Setif, Algeria But if those are not IATA codes, then I am probably completely wrong here.
