I'm not sure if this is the right place for this post, but it's a pretty cool story. Project Fear, a group hunting for the paranormal and UFOs, actually managed to record footage of a completely unknown US fighter jet over Area 51. It is currently unknown if it's related to the upcoming F-47, F/A-XX program, or something else. Credit to Project Fear for actually having a rigorous setup - multiple cameras (visual spectrum, multiple types of thermal) from different vantage points. The consensus in the aviation world is that the footage is legitimate, as far as I can tell.

Sandboxx News has a few videos on it. The first two are 5 to 6 minutes long, and the last is 30 minutes.

Screenshot of the video:

These YouTubers have so far contributed more interesting results than Avi Loeb and co! Kudos to them on the fantastic work!

The filmed craft bears some resemblance to the McDonnell Douglas X-36 and the Boeing Bird of Prey.

Both of those are actually on display at the National Museum of the United States Air Force!
