My kid asked why I check the same bolt twice and I didn't have a good answer
We were looking at a Cessna 172's landing gear, and she pointed at a nut I'd just torqued and said 'but you already did that one'. Has anyone found a simple way to explain our double-check habit to non-mechanics?
My old instructor used to say checking twice is how we talk to the metal. It's not that we don't trust our work, it's that we respect the consequences too much to just assume. I told my niece it's like making sure the front door is locked before you go to bed.
