Reflective disk in broad daylight, headed at 11 degree bearing (south, slightly west)

I was driving southbound on Woodman at 5:31 PM today, July 19th of 2023 (writing this at 6:35 PM). Saw a shiny, reflective disk (shiny but shadowed on bottom) just like the one at 4 minutes, 13 seconds in The Phenomenon by James Fox. Was heading south, slightly west, away from Wright Patterson Air Force Base. Disk appeared to be roughly 300 feet in the air.
I could immediately tell - this was absolutely not a plane. Regardless, all options must be ruled out, so once I got home (15 minutes later), I checked numerous flight radars to see if there were any planes passing the surrounding area in said direction - nothing, at all.
Object was not visible for approximately ten to fifteen seconds due to trees, after which I pulled into a very open parking lot in attempt to relocate object. Was completely gone, not visible whatsoever. Weather had clouds in the far distance, but was (still is) fairly clear in my relative area.
I've seen things that were "hmm, that's kinda strange… could have a prosaic explanation I'm just not thinking of…" before. This was very, very obviously not a plane. There was no exhaust emitted from this object whatsoever. No trail. It was very, very obviously not a balloon or drone. I'm very confused as to what this was.
