I didn’t look at it that closely.
Regardless ... there will be people who WANT to believe this is a “UFO”.
Hey look, I agree with you that some guy probably built this thing in his garage. Most likely terrestrial in origin. Still, it's unexplained, and apparently uses a technology for flight that is unknown to me, at least (assuming the photos aren't doctored, of course).
That makes it interesting no matter where it's from.
