Several of these phenomena the last several years. Some were attributed to rocket testing, as was this instance. Some were attributed to the northern lights. A few have gone completely unexplained. Such a wide-ranging area, bay area and la area. Testing a rocket over water would be safer than over those urban areas; but why not test it in the test ranges in the desert? There are areas inland designed for this type of stuff. To lessen the human impact of a failure in the rocket. It doesn't make too much sense to test something in a public display that could still be technically marked 'top secret.'
Is it the northern lights?; are they reflecting off the rocket fuel?; are they reflecting off the protons, electrons, neutrons and all the other particles of an unknown universe? Do you know what you think you know? A rocket that went bad. A light that went bad. A nothing that went bad. We don't actually live in the Twilight Zone, but these things are happening all around us, all the time. The FAA knew something was up when they grounded the flights. The Military is in 'it was all a test' mode. From what I've been able to gather, they were as flipped out over it as the FAA. They're lying otherwise. Unexplained Phenomena from an Unknown Universe. Only certain people should have certain answers and have the ability to lie to you and say: It was all a test. We know what is best for you. Believe us.
