Spell something
Type a word and read it out the way a pilot would.
Why these words and not others
B and D and P sound identical through static. So does M and N. The fix is not to shout louder, it is to say a whole word instead of a letter, and to pick words that sound nothing like each other: different vowels, different rhythms, different lengths.
Two of them are deliberately misspelled. Alfa has no ph, because in many languages ph is read as p. Juliett has two t's, because a French speaker would silence a single one. The alphabet was built for people who do not speak English, which is the same instinct as a hazard symbol.

Two words that are not English
Mayday comes from the French m'aidez, help me, chosen because it survives a bad radio. SOS was never short for save our souls: in morse it is nine even beats, ... --- ..., which no operator could mistake for anything else. Both are engineering decisions that came out sounding like words.
And Roger means R. In the older alphabet R was Roger, and R stood for received. The alphabet changed, R became Romeo, and pilots kept saying Roger anyway: a word that is the fossil of a code nobody uses.
