But hey, to answer your question:
1. Have you ever watched a missile launch live?
Yes. Many times. At sea, even.
2. Have you watched more than five missile launches live from a range of 160 miles or less?
I've watched many more missiles than that, launched at sea right over my head, and at distances of 20 or more miles.
3. Have you lived for a year or more in the greater L.A. area from Malibu to Newport Beach within 25 or 30 miles of the coast?
No, but I served at sea for four years, off the coast of California, Mexico, Oregon and Washington and Alaska.
4. Have you watched both airplanes and missile launches with the aid of binoculars?
Yes. Even with "bigeyes" (80x200 pedestal mounted binocs). Back in the Cold War days, it was important to be able to tell the difference.
5. Have you watched this video?
Yes.
Any further questions?
I don't even HAVE a conspiracy theory, if you notice! Again, like Werhner von Braun might say, that's not my department. I would be totally out of my league trying to even guess.
But it is well within my league to look at that video in the context of the region where it was shot and surmise -- accurately -- that it shows a missile launch. Pure as day. I am too familiar with the area to think otherwise.
You've watched missile launches. You've watched the video. The lighting of the setting sun clearly shows that it's headed northwest. You know that people are claming this object is supposed to be a plane headed north-east to an airport a scarce 50 miles due east from the camerman. Honestly -- how on earth can you square two conflicting items -- the direction and the distance and elevation such a plane would have to be -- with the idea that it was too far away to tell if it was an airliner or a missile?
