Interesting thoughts! I'm not sure the alignment pin is the culprit. And even with a good alignment pin, if the latch is not locked to the frame, it can move and allow a release. I think if I forgot my locking pin the spring would still hold it. And if my alignment pin failed, my canopy could only move back a little before it hit the turtledeck bulkhead.

Regarding the Waiex video, there was no twisting until the canopy lifted. Then it was game over. The canopy is flimsy when open, but plenty strong when latched. If they had pinned it, or even if they had the spring to prevent the latch from migrating back, that would not have happened.

I don't know why the picture is upside down....

Interesting. I like the idea of a large handle that has an obvious visual that it's not latched. Do you have any pics on how it actuates? FYI... it's the right way when you click on it. (Not upside down)
