Still trying to figure out..... Why would you want to land INVERTED, let alone do it enough to find an inertia bug?

The simple solution, land on your wheels or your belly.

If you land on your head, you should not have a landing at all.... you should be a red-paint stain on the runway. I could be wrong, but I would be curious to know how many WWI planes were equipped with roll-bars to prevent the canopy from collapsing on enterprising young pilots who could not figure up from down.
