I don't think the Cassutt ever had aerobatic approval.
Colin was an entirely new design, albeit based on the Cassutt.
I was given to understand that a previous incident of being kept at the hold for an extended period had caused the engine to overheat earlier in the season. This may have caused the initial damage that ultimately resulted in a non-standard smoke system during the somewhat shortened display.
Anyhow, bit of thread drift there. I'm sure the linen-suited man has recovered from his adventure and will be in a position to finance a rebuild for what looked like a very pretty Moth. It would be a shame to see it go to waste.
