What's the most unexplained UAP video?

I'm about to teach an online class in critical reasoning, and we're using UAP videos as the content. I'm looking for videos that have survived attempts to debunk them. An AI suggests Gimbal and TicTac... but I already find the more mundane explanations by (for example) Mick West to be pretty powerful there. If you wanted some thoughtful, open-minded kids to take UAPs seriously, but you could only show them one video, what'd it be?
