Happy to hear both survived with minimal injuries.
What would it take to prevent the aircraft from going over on its back?
Often wondered if adding some means of drag to the rear of the aircraft would prevent overturning.
Example, just before touchdown pull the pin activating a grappling hook with spring loaded unfolding claws, attached with 100 feet of low stretch high performance sailboat line, spring loaded from a 1.5? dia or so PVC tube. A small drone chute near the hook to prevent slingshotting into the rear of the aircraft and also provide drag for a water landing.
Have not thought about a nondestructive means of testing.

I saw Wile E Coyote try that once, it didn't work for him.

Sounds like a great way to add a LOT of weight way in the back on the off chance it might be used some day, but only if the pilot remembers to activate it.

The track record of RV flip-over crashes, where the pilot flew and controlled the airplane all the way into the flip, has been pretty survivable.
The track record of task-saturated pilots in emergency situations, resulting in stall spins, has been much less favorable.
I'd save the weight, and focus on flying.

I've never seen that thingy ma jig the firemen are using to flip the plane back upright. The video stops short. Anyone know how it completes its task?

Looks like it's a variation of a cherry picker for removing car engines.

They are using stabilizing struts. We typically use them to stabilize a vehicle when we need to extricate a patient with rescue tools "jaws of life".

Anyone know how they got out? One of the big question marks in my mind if I have to try someday.
