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?


I am now working on a new design and have been trying to find some
simulation software that can do a decent dynamic stability analysis through
Mach 3 but have so far been unsuccessful.


Would any of these help?
