I saw a bright object resembling a plane with one wing go across the sky and a fake cloud with super fast disc fling underneath it

I saw a bright white object with a small fire like trail behind it. After recording the uap, I turned around and saw an unusual jet stream in the sky so I recorded it. I then noticed afterwards that there was a funny shaped cloud hovering around other clouds slightly moving left and right. I took the video recording of the cloud and edited the video cropping it and re-recorded it in slow motion and you can see a small disc like object circle up and then around the fake cloud and go underneath It was moving at a very high rate of speed going under the.fake cloud,
