If you saw my Starburst CATO is looked like a lot of smoke and spinning rocket parts. At work I was able to play the attached mp4 file frame by frame several times which allowed me to see what happened. The engines were two Estes E12-4's.
It was not a conspiracy or a gunman on the grassy knoll.
Both engines fired.
The rocket lifted off.
The right engine blew through the top ejecting the chute.
The left engine continued to burn moving the rocket forward.
When the chute opened it caught air and interrupted the upward trajectory of the rocket.
The rocket was fighting the chute but the chute kept pulling it down.
When the left engine stopped burning, the rocket came down under chute.
In one of the later frames you can see me cringing.
Believe it or not there is no damage to the rocket.
Does anyone have software that can play the mp4 in slow motion?
If I remember correctly, several people had CATOs with E12 engines.
