In the 1984 Ghibli film Nausicaä of the Valley of the Wind, before the Tolmekian ships arrive in the Valley of the Wind, the corvette uses a signal lamp to communicate with the mother ship:

The corvette (the smallest ship)

The mother ship (the biggest ship)

I assume the signal is based on Morse code (because it blinks). What is the communication about?

  • The scene takes place around 29 minutes into the film.

  • @Joachim 28:38 to be precise, thanks for mentioning that. I totally forgot to specify it.

I decoded it as best i could and tried using context to understand the messages. The first message sent by the corvette was "- ..- .-.. -.... -.." or "TUL6D". It seems like gibberish until you understand that Morse Code signals have a lot of word and sentence simplifications and I had to use a lot of context to try to figure this one out, but I think I know what it says. TUL could be a simplification of Tolmekia and how you pronounce the first part, as for the 6, that is the number of airships in the convoy (One Corvette, Five Bumblecrows). Using this evidence, we could safely say that TUL6 means, "Six Tolmekian Airships". as for the D, I think it is a one letter simplification of "Move Down." Putting both parts together, we get "All Six Tolmekian Airships Will Move Down." The Bumblecrow responds with ".... -.. .- -.-. - " or "HDACT" Which I really struggled to figure out, but I think it means, "Heading Down Affirmative, Confirmed Target." That target being the Valley. Do not take my words as verbatim, but I might have figured it out
