a large meteorite just happened to collide with earth's atmosphere right after two satellites collided?
First of all, we can't tell how large that meteorite is in the video, and secondly this was about a week after the satellites allegedly collided. Hardly meaningful or connected when thousands of meteorites hit the earth's atmosphere every single day.
A meteorite that looks like a fireball ? It looks like this:
That's very similar what the video in the OP looked like. However, the meteorite in the OP was significantly less pronounced.
The FAA gave orders to pilots to watch for falling debris. They were expecting some to fall to Earth.
Yes, I'm sure pilots were dodging those falling satellite pieces left and right like a warzone.
