"1 A crew module sized and weighted to represent Orion will ..."
So, the Boilerplate is an accurate representation size, shape, weight and
center of gravity and therefore should fly the same as the real thing.
Orion, unstable in SubSonic Flight, will spin so fast that it will
incapacitate the Crew preventing them from taking any actions to save their
own lives.

Mickey Mouse has big balls if he is going to ride in this "unstable" death
trap.
Back in the Day, the Space Shuttle was designed to withstand two
failures. A concept of Fail Operational, Fail Safe. First Failure causes
an abort, ok, good. Second Failure no parachutes, ok, good.
I would have expected to see a nice STABLE Capsule smash into the ground,
giving the Astronaut plenty of time to "Work the Problem", fix the
Parachute or Blow the Hatch and jump out . Instead, I was treated to a
high RPM gyro ride that Disneyland wouldn't touch. The Simulated
Astronauts may have even died before hitting the ground. There was no
"Manual Override" even possible, no Bailing out with a Personal Parachute,
no saying goodbyes.
It's NOT hard to build a Stable Capsule, just look at a Soyuz Capsule.
Stable in hypersonic flight. Stable in supersonic flight. Stable in
transsonic flight. Stable in subsonic flight.
Comparing the changes made to Orion from the original Apollo design, the
"shape" changes would tend to make it more unstable. Orion may even be more
stable upside down, flying heat shield up.

Those High Temperature Tile are a great idea for a capsule that is more
stable Up-side-Down.
The Operation was a great success, but the Patient died.

It was a boilerplate crew module, without a parachute recovery system.
Once the crew module separated and was out of the near-field flow field
behind the launch abort system, the test was over.
The flight data was telemetered to the ground. As a back-up, ejectable
data recorders were used as a second means to get the flight data if there
was a telemetry system failure. The ejectable data recorders were ejected
after crew module separation.
After reentry from orbit, or after an abort, drogue parachutes are
deployed. (There are modes where you go direct to the main parachutes.)
As the boilerplate crew module had no parachute system, it had no drogue
parachutes.
The crew module has to be stable after separation from the launch abort
system for a short period of time before deployment of the drogue
parachutes. (Or for the short period of time before you go direct to the
main parachutes.) The crew module was stable for this short period of time.
Tumbling later in the flight shows why drogue parachutes are used.
Drogue parachutes are lighter than other options of reconfiguration of the
outer mold line, Center of Gravity (CG) shift beyond what is built into the
capsule for a small Lift-over-Drag (L/D) ratio during hypersonic reentry,
or other options.
As I noted; after the crew module separated from the launch abort
system, the test was over.

Subject: [AR] Orion Abort Test Failure...
...Not Human Rated. Orion Abort Test was a complete and utter failure,
yet NASA calls it a success?
I can make some assumptions about what they did, like. The shape of the
Orion Capsule is correct. The Center of Gravity (CG) is correct. Given
these two assumptions, this Orion Capsule test was a complete and utter
failure. Back to the drawing board and re-design the entire Capsule, it's
not Human Rated.
NASA showed this

Yet, here is what the Orion Capsule flying through the atmosphere.

I would hardly call this "Stable" flight. Exactly how many RPM do NASA
Astronauts like to be spinning at, when they impact the water? Gees, can
you imagine what it would be like to "Work the Problem" tumbling at that
rate?
The Orion Capsule is unstable.
