Where the alphabet comes from: the code words and their “spoken as” guides were copied from Appendix 14 of the ITU Radio Regulations; aviation numbers and number rules from the UK Civil Aviation Authority’s CAP 413 radiotelephony manual, with the FAA’s list as a cross-check; numbers at sea from the IMO Standard Marine Communication Phrases; and history from NATO’s own history of the alphabet and Alistair Edwards’s study at the University of York. All checked on 31 October 2026, and listed on each pack’s credits page. Drawings, puzzles and layouts are REALLYBYTE’s own work. phonetics.languages.im and REALLYBYTE are independent and not affiliated with or endorsed by NATO, ICAO, the ITU, the IMO, the UK Civil Aviation Authority, the FAA or any government body or armed force.
