The Leyvas video was taken to the south of the event. That is interesting. Gil Leyvas position was well to the north of UPS902's scheduled flight path. It was even to the north of Catalina Island. He also categorically stated that he thought he saw the contrail of UPS902 far to the south of what he was taping and where he was.
He (Gil Leyvas) thinks it was far out to sea, behind/northwest of UPS902. He does believe he saw UPS902 far to the south of the object he was viewing, because he specifically compared that contrail, which was obviously a jet liner, to this object, which was NOT obviously a jet liner.
If your argument holds up then we can eliminate UPS902 completely from any further speculations.
My mistake. You are correct that Gil would be north of UPS902 assuming at least some of the video was shot from the vicinity of Long Beach. But since it isn't hard to plot what he was shooting with respect to Long Beach, (see 1:37 of this video
KCAL video report), and TXnMA actually has plotted that here...
it is pretty hard to claim UPS902 was "far to the south" of what he was filming, since the actual UPS902 ground track lines up almost perfectly with the site line of what he was shooting.
"He (Gil Leyvas) thinks it was far out to sea, behind/northwest of UPS902."
Really? At 1715 (when Leyvas said he started shooting) UPS902 was 175 miles from Long Beach. So if he thinks what he was shooting was even farther away than that, I'd love for someone with more brains than I to calculate the width of the "missile trail" depicted in his video.
