Video footage of an UAP – user profile of original post has since deleted his Twitter account

Found on Reddit. The weird thing is the listed source on Twitter https://twitter.com/UAP1949 BUT user’s account has been deleted. If you search Google for “UAP1949” you can see they were very active on Twitter / X . Some articles about UFOs/UAPs have the user’s quotes on their webpage.

What do you think it is?
