How the heck do airplanes not crash more often? To my understanding, there are millions of wires and pieces that all have to be working perfectly to keep a plane in the air, how is there not more crashes?

Question

Ive watch every mayday episode and tons of crashes are caused by like a simple screw being put back wrong after maintenance, how the hell do all these planes get good enough inspections done even fly several hours without failing and falling out of the sky?

Answer 1

I’ll add to the other answers this: Many many years of testing and refinement.

When a problem happens, especially a fatal accident, the FAA, NTSB, the manufacturer, airline and probably others do an extensive investigation. This adds to the body of knowledge about what can go wrong. If it’s at all possible, procedures or technology are put in place to prevent that particular problem in the future.
