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?
