What are your personal favorite r//UFOs posts of all time?

Those of us that are relatively new to this subreddit and the topic can easily sort by top of all-time, but I think those posts don’t give a full picture of this subreddit. Those highly upvoted posts are often upvoted without good reason. There are some videos there that are still confounding now, but many of them are well faked videos (or even poorly faked videos), or are just sensationalist claims without backing. Sometimes, the thoughtful, well-researched, or even groundbreaking posts are not recognized as such and are lost to time. Even though this topic has evolved, and is still evolving, I’d bet many of those old posts you seasoned veterans remember are still very relevant now. Even if they’re not, it would be interesting to see the history.
