Ouch, sorry to see that. What motor did it go up on?

K1103

The frost did a wonderful job of not dissipating the energy…
The only part that penetrated the frost was the aluminum tip, which he recovered…

Not much you can do about that one now except learn from the experience. ALWAYS arm the electronics before inserting the igniter to prevent a ballistic return. As the rockets get more complex a checklist becomes your friend. Create one and let it evolve as your rocketry progresses.

What about having a remove before flight tag taped to the rocket that you only remove when the electronics are armed?

wow, all that work you put into it. sorry to see that.

Well here ends the Punisher build, I salvaged the motor retainer, reduction ring, and drogue parachute.

That really really sucks. I had a ballistic rocket on an L2 attempt. 3" Honest John pushing mach 1 on a J435 and the motor actually failed to ignite the powder. All we heard after it going up was the whistling sound of a bomb being dropped and then it hit about 20 yards from the flight line in a thud.
