That was something I intended to mention as well but forgot, I LOVED that you included links for further information for the real-world events that inspire the mission, I did a bit of research into Cairo for my own submission and found out a lot about how the opera house featured was the first in Africa, but burned down in the 70s and now the site is a multi-story car park which is really sad.
That's very cool regarding the cassette tape, though I know how painful it can be to write a lot of copy that never gets used because the party takes an alternative route, maybe that is why sharing my creations is so satisfying because at least someone will see it other than me :D
