The damage isn't even as bad as I would have expected considering you only had one good chute and a nose down trajectory. And I'm with Neil, I want to see video!
One out of four chutes was enough to save it from a major kink or break of the launch lug. The heat from the motors also softened up the aluminium tube a bit making it a tad weaker. I would speculate the motor that blew out the back was the first one to eject, the nose cone with the most damage and the cheap Estes chute just stripped. The motor hit the fin and took a chunk of balsa with it, this was reported by a Top Man observer who said he saw it clearly. So that was just some of the fast paced action happening at ejection, little bits flying everywhere, balsa bits, motors, ejection nose cones/shock cords, chutes ripping off and deploying. It landed close to the pad, in the range, so a nice short recovery walk. Straight up, arched over and straight down.
I had packed it up a couple of weeks before and did not repack before launch, so the dog barf might have got a bit compacted. But with the minimum diameter, tight pack, ejection charge pressure on the nose cone and cap, I will take both the nose cone and motor blowing out.
