CORRECTIONS
- If you watch very closely: I misspoke twice while filming and fixed it in post. See if you can spot them!
- Not a correction, but more of a fun fact: the plane that flies over me at the start is an A380. How amazing would it have been if it was a Boeing 787‽
- Nothing else found yet. Let me know if you spot anything!
