Watch the video here: http://latimesblogs.latimes.com/lanow/2010/11/video-catches-mystery-missile-launch-off-la-coast.html
There is a helicopter in the forground, and you can see the jet crossing over the top of it. That means the bird is moving eastward, not westward. An object moving westerly would be receding.
I did watch that video and that is no commercial jet. I’m sorry, but to say that is an inbound for Phoenix is ridiculous.
The missile is 35 to 50 miles away. When did it achieve an elevation higher then that helicopter ? You do not know. The helicopter position is immaterial. Look at the plume. The lighting. It is the key. Bright on the right. Dark on the left. Missile arcing toward the setting sun. Arcing west. Indisputable.
