Have many versions about these costum of use code for the first letter of the words. All is basement in two things:

1- Take clear for confirm de correct word normaly used in comunication at long distance, by radio, phone and others than used the sound.

2- In oposite take a confusion for peoples thath don´t know the (linguage) code used in a comunication.

About the alfabet that you told I think was first used in the second word war by the USAF for take a confusion by the enemyes (Germains and Japaneses) doing association for confirm the correct first letter at the segund world war used in the American Indians (Navajos, I supose) becouse before that the enemyes was doing the traduction of comunication betwhen airplanines pilots, or the base radio and frustredin the atack planes, or shutting the airplanes in the coordenates exactly where it was.

Please pardom me my English isn´t so god, I´m learning by use the Yahoo answer.
