If my flight is the one you're talking about, it was coning or pitch-roll
coupling that eventually caused the airframe to fracture just in front of
the aluminum coupler. The rocket was over stable and one fin was not right
which caused the rotation to begin with.

There were, shall we say, some stability issues, and the rocket came
apart at about 5 seconds into the flight.

Was that was the spiraling one you sent us the video of? That was an
engine mount failure, wasn't it?
