The atmospheric conditions changed momentarily and the contrail stopped. You realize the atmosphere isn't uniform right? It can change a LOT in a very short distance or even in the same spot in just a few seconds.
When I flew sailplanes, I was ridge riding one day, and went from a 1500 foot per minute sink rate to a 6000+ (my gauge stopped at 6000) foot per minute climb rate, to a net zero rate in about four seconds. We turned back to look for the thermal to ride it, and by the time we got back to it, it was gone. That's how fast things can change.
As for the altitude in the video there's no way in hell that is "6,000 feet".edit on 10/6/2013 by Zaphod58 because: (no reason given)

They were at different altitudes with different engines. A C-17 engine will produce a contrail where an E-3 engine won't.
I'll believe it when you have a hell of a lot more experience with aviation than I do, and post something besides a BS YouTube video.
