See what the inner fuel tanks look like during a launch if the rockets were transparent:

   Fascinating, Brian, thanks.
   Brings up a bunch of questions, about those ROCKETs in comparison.  RE: Those solid boosters;

   Looked like the solid boosters generally burn, in that center well, and so the question is, does that 'burn' extend all the way, up and down the cylinder ? (Rather than some pattern like burning the solid propellant from bottom up).
Of course, that would be, about, a 43 year old question, now.

Each of the SRB segments are basically the same and burn from the center out. The shape of the hole can be used to control the burn rate and therefore the thrust to some a degree. I'm pretty sure Scott Manley has a good video on solid rocket boosters.

Watch the video again carefully looking at the solid rocket boosters.  When they start, they have a thin long central tube where all the propellant burns, top to bottom, pushing through that long tube opening.  As propellant burns away, that tube opening widens until it's all gone, reaching the rocket's outer cylinder.

That is the level of what I know, but Youtube search 'Scott Manly SRB or solid rocket boosters' and he has a few detailed video on the subject.
