Good Grief!! Buy you books, send you to school, draw you pictures -- and you are still tossing up crap that I disproved long ago and over and over. Are you totally incapable of reading and learning?
That guy with the camera shot of his TV screen is talking about one of the "cross fades" or "cross wipes" that I show at :13, :29 and :33 here -- where I first exposed SeeBS's lie about their deceptively edited short film clips.
That is no second contrail. In a crossfade transtion, frames from two joined clips are simultaneously visible as they both pass through 50% transparency.

All you did by pointing that stupid "video analysis" out is reinforcing the clear FACT that you "missile truthers" have been suckered by a SeeBS "sweeps week" LIE!
