Was this a rapid SCHEDULED disassembly? How was it done?

Question

The new Curious Droid video Apollo's Forgotten Computer - The LVDC discussed the Saturn V flight computer that's also discussed in answers to Is this really the Saturn V computer only, or are there other systems here as well?.

At one point there is a discussion of the Launch Abort system and a few seconds of file footage is shown.

In addition to the launch abort rocket igniting, at about 11:18 the video shows a rapid disassembly^† of several rocket components.

Was it intended for the rocket to "fall apart" like this into so many pieces? If so, how is this accomplished?

^†Who coined the phrase 'Rapid Unscheduled Disassembly'?

Answer 1

No. I think this is actually the May 23, 1965 A-003 test, described in my answer to the question, Could a spacecraft spin so fast that it spontaneously deconstructs?

Notice that the rocket and Apollo CM are spinning. That isn't supposed to happen. In A-003, improperly installed gyros caused the vanes on the fins to deflect fully in one direction, imparting a spin that accelerated. Eventually this caused breakup of the Little Joe II rocket that triggered the actual abort.
