No, that’s not what I mean.

Show me any video of what you just described, however, remaining in view for 8 to 10 minutes, and I’ll grant you your point.

Oh, now you want 8 - 10 minutes even though you can only stretch this with the uncertain possibility of 4 minutes and 53 seconds based on Warren's supposedly time stamped pics. I say supposedly because only a few are labeled with any time stamp on the Contrailscience.com website.

I think I'll stick with Gil Leyvas' estimate of 3 minutes maximum.

You want me to produce a video of a missile launch that shows an exact reproduction of Leyvas' video which could only happen if it were taken under the same conditions. That's not going to happen.

But this one does show a lot of similarity even though the second stage is powered flight. In the first stage there is a continuous plume, in the second stage there is a plume that doesn't persist long and very briefly after that there is a small tail plume barely visible even though the third stage is a solid rocket motor also.

This video doesn't show the contrail after the vehicle is gone for 8 - 10 minutes, as Leyvas put it, but it does show a few similar things.

It takes almost four minutes to fly out of sight. It begins with a very thick plume which diminishes to near invisibility even though it is under power the entire time. The audio picks up no sonic boom even though the cameraman is almost directly under it. The flame of the rocket motor is obscured much of the time. Its flight describes an arc even though it is being launched into orbit.
