I had the same thought many times by myself when watching UFO shows.
It looks to me like a large balloon or giant garbage bag or very large packing debris of some kind that became airborne somehow and is just blowing around in the upper atmosphere. That's what many of them look like to me.
Oh look! It has no thermal footprint! Well .. yes. Because it is paper or plastic of some kind. And at night, who knows how many or what color lights may be reflecting off of it.
Maybe there are some legit videos of actual craft travelling against the wind. Maybe? But most of the ones I have seen look like airborne trash of one kind or another.
