They’re locked down tightly and really difficult to do so on. One I have would require opening the back and doing stuff under the hood… Seems scary…

Hmm, yeah, that makes sense because if it folded backwards, well, if the plane were landing with more force than expected…!

I wonder at what point repairs would be satisfactory for engineers to declare it usable again. Would it need to go on an empty test flight exactly along its normal path to be declared “safe enough?” What’s the minimum incurred damage at which a plane would be considered totaled?
