The people pushing the airplane scenario are going to tremendous effort to get good people, honest FReepers, to look at anything BUT the video.
Notice how according to the airplane pushers, still shots of other events, airplanes and missile shots, are perfectly acceptable for comparision and study, but somehow any clip from Leyvas' video -- a clip being the equivalent of still shots being shown one after the other in order -- is questionable. Then when you say, Okay, let's look at this still shot from Leyvas' video, those same airplane people turn around and argue that somehow, becuase it is a still shot of the video, that it's not representative of the event because of editing done on Leyvas' video.
I am dismayed at how many FReepers are such easy prey, and who have so little confidence in their own abilities that they submit to phony "experts" like the sources behind contrailscience and Rick Warren photos, whose photos may or may not be of what they say are, while the Leyvas video's authenticity -- taken Nov. 8 off the Los Angeles coastline -- is so certain that it's not even in dispute.
This contrail is of a plane that came over LAX at very high altitude and landed at Ontario Airport further East. Given the right conditions it will happen ever day since this is a scheduled freight flight ~ and observers have found this to be so.
