All this was posted by me in discord so I’m tranferring it here:
When you open this link to wiki, provided by Desmond, it opens to a photo of the world with some missing pieces of the puzzle. - https://www.wikipedia.org/
Desmond also mentioned his B-17 and B-52 model planes
I also think the Morse code is not something to unscramble but are codes that are part of the List of RAF squadron codes.
When you put Dia’s Morse Code hint into Wiki, it leads to this link - https://en.m.wikipedia.org/wiki/List_of_RAF_squadron_codes
which are part of the List of RAF (Royal Air Force) squadron codes
And your artwork of the flying snake looks a lot like the - British Army Air Corps 670 Squadron Embroidered Crest Badge Patch -

(This badge image was found on Amazon.com)
Is this the missing hint?
And this might be your pup because the B-17 and lots of planes during the war had nose art of beautiful girls
And once again, my head is in the clouds
And everyone is probably glad this is a short story and not a full blown novel.
