We just learned about the International Maritime Signal Flags.
There are flags for every letter of the alphabet, like the Alpha Flag, used for the letter A.
People can just use these flags to spell things, and each letter flag has special meanings too.
All by itself this flag eans "I have a diver down; keep well clear at slow speed."
The shape of this flag is called a swallowtail, and the colors are "argent and azure" which means white and blue.
