A missing o-ring (in the motor delay section) led to the rapid demise of the forward closure of the rocket motor casing. This creates a rapid “air brake” of sorts, as the pressure now escapes forward through the rocket, scorching everything inside. At full size, you can see propellant debris showering down from the U-turn event.

It was quite a spectacle as Erik’s rocket burned the whole way down, and fried the chute. (next frame)

  1. looks like the fins are still intact…

  2. I did this to one of mine, it was on a smaller motor so it didn’t get very far, but it’s now a "static display model" due to the internal destruction. Hurts, but I took the lesson "never assemble a motor in haste" from it, and haven’t done it again.

  3. It looked so peaceful on the pad…

    Anticipation

    I think the fins are in good shape. I will to salvage the entire fin can and add a new body tube…one that can hold a new high resolution video camera =)

  4. "A missing o-ring led to the rapid demise…"

    Always remember the O-rings! (But don’t buy them from Thiokol….)
