Does anyone remember when people filmed a sawed in half UFO being transported on a highway?

Why nothing else was known from it? People supposed it was a prop for some movie but I haven’t seen it anywhere, this happened more than a year ago.

I remember there was a recording with a police caravan that was escorting a trailer with another half, except this happened at night. The internet has a short memory but I wanted to know if anyone knows what else came from this.
