Hello @eve66. Thanks so much for participating. I love your story explaining the happenings in Jeremy's time:
"A programming specialist is working on an ultra-secret project. The setting is the future, where Artificial Intelligence sends signals to prevent catastrophe and warn humanity."
Awesome. This can be a foreshadow by the unknown girl in the restaurant.
Now, the specialist is only using info he/she believes is accurate for Jeremy's time period; hence having the airplane send the message. Love this part. Your future explanation can fit perfectly with @myjob's version that someone or something is controlling the happenings. @myjob even applied meaning to the roman numerals.
I'm beginning to see a backstory and possible ending thank to you all's contributions.
I appreciate your contribution. Take care and have a lovely weekend.
