During the most recent SpaceX launch, a timelapse photo of the trail left by the rocket was made. http://img.new.livestream.com/events/000000000031d6a7/93d34713-b8a1-4e7a-bdd8-f52c2580b004.jpg
This image is pretty awesome to look at, and it’s virtually a 3 dimensional graph of thrust angle and magnitude versus altitude.
What’s with the large change in the middle there? Is that the throttleback near max Q or just an artifact of the way this image was taken?
