Why 9A-ZAG?

9A is the International Telecommunication Union and international aircraft registration prefix for Croatia

ZAG stands for Zagreb which is capital of Croatia.

NINER-ALFA-ZULU-ALFA-GOLF is a way to pronounce 9A-ZAG with Spelling alphabet (also often called a phonetic alphabet) widely used within radio communications.

Although this page does not have anything with aircraft transportation or radio amateurism I find this name very convenient as domain name. It means: CROATIA-ZAGREB (HRVATSKA-ZAGREB)
