But there is always a gap, even if only a few tens of feet behind the plane, before the exhaust condenses water vapor in the air. And there are always separate trails from each jet engine for a distance before they merge into one. Nowhere in this film, even when zoomed, is there a gap between the vehicle and the contrail or separate trails from multiple engines. The contrail immediately billows from the vehicle instead of gradually dispersing as a vapor trail does. It looks nearly identical to the contrail of a shuttle launch.

Yep. But it is not apparent when the plane is coming at you. Just as you don’t see the gap between a car and a trailer when it is coming at you.
If a lot of people will just humor me and watch the video with the mental assumption that it is a plane headed generally east, a lot of things clear up very well.
