It was cylindrical but wider than tall, had metallic looking panels, was not moving, no sound, no lights, no windows.

While driving east bound on 10 fwy, I saw this cylindrical object just past the end of the runway at Ontario airport, maybe one or two miles. The object was not moving. It was in the direct flight path. It was at the correct altitude of a plane coming in for landing. The craft was cylindrical but wider than it was tall by at least double. The object had shiny metallic looking panels. From my viewpoint the center panel was taller and wider than the panels next to, as they wrapped around the object. I believe there were at least five large metallic panels. Some smaller panels. The reason I noticed it was because it was stationary. It was difficult to see, at first, because the color looked like different shades of metal, from dark, almost black to shiny almost white. Behind it were the San Bernardino mountains, which were gray brown. The sky was clear. Once noticed the object was easy to see. It made no sound. Had no lights. No smell. No windows. Did not move. Hung in the air.
After seeing the object on 8/4/2022 I forgot about it completely. Then on 8/25/2022 while driving past that exact location, I remembered it again. Then quickly forgot it. Yesterday 10/4/2022, while driving on the 10 freeway in that exact location I remembered it again. During the day I repeated seeing it in my mind to try to remember when I got home so that I could write it down. Not only do I remember it today but I did a sketch of it. The object was a bit darker than shown. It had more panels than shown.
