the NATO alphabet. (Alfa, bravo, charlie, delta…) It’s surprisingly easy to memorize: - HN

• HN about 30 years ago I read the same thing, but I found that code much easier because it rhymed with the numbers:
  • 1, bone; 2, shoe; 3, tree; 4, door; 5, hive; 6, sticks; 7, heaven; 8, gate; 9, line; 0, hero.
