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?

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?

This is incorrect because aircraft have redundancy on critical systems. They don’t have to be perfect to fly, in fact they’re even allowed to take off in some situations despite known existing faults. That’s not to say that a single screw missing can’t eventually cause a crash in very rare circumstances.

In short, aircraft are designed, to the extent possible and economical, to keep flying and save lives even in the event of a fault.
