in the paragraph you quote, it is indeed interesting that the SRB is
stated to be rotating clockwise, given that the only SRB that is obviously
rolling is the one sporting a flare and seen to be rotating CCW (viewed from
aft) in various video clips.
You provide no links to support these two claims; no one should have
to take your claim about "obviously rolling" and "various video clips"
at face value.
However, in another section of the Report, the SRB is identified as rolling
in the same sense as seen in the video clips (CCW):
Again, you provide no links to support your claim concerning video
clips.

As the SRB continues to fly away, its counterclockwise rotation and
varying angle-of-attack cause the appearance of the flare to change
drastically.

No aspect angle is specified; your point is therefore impossible to
verify.
What you have done is proven a typo - not uncovered a mis-identification.
Don't be absurd. The video evidence cited in the 51-L Radar Report
released by the Air Force is *verifiable* evidence. Note that the
Ponce de Leon MIGOR tracked the flared SRB *continuously*; there was
no extrapolation from early, ambiguous "clips:"
"It was tracked continuously by Radar 1.17 and Ponce de Leon MIGOR."
The PDL boresight video unequivocally verifies the "clockwise" claim
made by the authors of the Radar Report, particularly from t+90 to
t+110 seconds, when the angular momentum of the flared SRB increases
due to fuel depletion, and after the dangling aft flare has been
shortened because pieces of it have burned away and dropped away.
You have reviewed that video yourself, as have others:

Furthermore, the UCS-10 boresight video (and the E201 film) confirm
what the PDL boresight video proves conclusively. I fully expect to
be using all of the above in an upcoming series of academic lectures.
