look at 2:54, look like the same effect but a bit clearer. I am gonna leave it there.

is how a downward track of the chase plane camera, CLEARLY banking or descending has a "reflection"Because the camera is tracking the B2. It is not following the maneuvers of the chase plane. The camera is not in a fixed position. It is being aimed by someone. Aimed at the B2. So when the chase plane rolls and the cockpit reflection moves, the B2 stays in the same place and the reflection moves.
I guess I'm asking... what kinda move did the plane make to show us that awesome video footage that has us all fooled?It rolled left slightly and you are the only one who seems to be fooled.
All video shot from the front cockpit cam (fixed).
