While most people have never heard of the NATO phonetic alphabet, they have likely encountered it in use, at least in movies and television. If you can recall a scene where a pilot says something like "Alpha," "Bravo," and "Charlie" over the radio, then you have heard the NATO phonetic alphabet at work. It is a system designed to ensure letters are clearly understood, even over crackly or noisy connections. It's been around since the 1950s, but its roots go back even further. Take a look at some interesting and cool facts about it!
