Better than my experience a few years ago - pre warning system.
Doing the flight test/fly off for the owner (not builder). Unbeknown to me, he thought the canopy handle was too stiff, so he turned it through 180°.
You know what's coming.
I did the next flight and at about 110kts, the canopy came open. To be honest, no big deal, close the throttle, see where the canopy was floating - within reach.
Now, if you have seen the stage funny - Balloon Dance with the 3 naked fellows and some balloons - that is where I was. 2 hands and 3 needed.
Eventually locked the throttle at idle and did a glide approach.
Stern words with the owner, called it in to Vans and the LAA and I think that started the process of the warning system.
