San Nicolas island (part of NAS Mugu) is right under the putative launch point.
The raw video shows clear plume movement and a 'flame'. It's not a plane: this was a rocket.
Is there some “raw video” that different from all the video that keeps getting posted? Because the video that has been shown does not show this.
Plus, there’s no way they launched a missile from the ordnance range without filing to keep planes out of the area. Or without anybody hearing it.
