Craig: 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. Charles E. (Chuck)

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 thishttps://www.youtube.com/watch?v=4rfsDMGplZU
Yet, here is what the Orion Capsule flying through the
atmosphere.https://youtu.be/2RbbSGrO_tY?t=170
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.--
