Thanks for asking. I got the CERT flight out of the way early. It was successful on an H97J.
The shred you saw was on a H210R - a big difference!! Amazingly, enough of the fins was left on that it stayed stable. Someone found it and brought it back to the RSO's table. It was in perfect condition except for the two broken fins. I found the two broken parts and reattached them with superglue. It flew later on a F21.
Given its weakened state, I don't think it would fly again on an H. I'm considering whether to 'glass it or just build a new fin can with 1/4" ply.
