Then it's far simpler. Views from the north that show it going eastward with time.
There were flight restrictions near to that area and near to that time.
Doesn't matter whether there were restrictions posted or not, there were commercial aircraft flying through the area on schedule, and they were picked up and plotted on the radar records.
Adjust your theory to fit facts, not the other way around.
The lighting proves it was going westward. The Retired General on Hannity stated is was arcing at 45 degrees away from the video camera. IE - Westward. There is even a second video showing it going westward. That is why it appeared to be moving slow.

What area ? We do not know where it was launched from. Might have been launched way out at San Nicolas Island and quickly arced 45 degrees elevation out to the west.
