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?

On a commercial flight, several things are true:
– Your pilot has had well over 1000 hours of training.
– Your pilot is sober.
– Your pilot is well-rested (ideally, if the airline is following best practices).
– Your pilot has multiple other people, all under those same conditions, watching their work.
– The plane has been serviced regularly, which includes checks every 100 hours.
– There aren’t any other planes nearby – the approach, runway and flight path are all clear.

Compare this to a car:
– You can get a full license without a ton of supervised, formal training.
– You might be slightly, or highly inebriated.
– You might be tired.
– There’s probably not someone else watching too closely; if there is, they can’t access the controls.
– Your car might have been last serviced months ago, or longer.
– You are sharing the same little space with dozens of other drivers, all of whom share the same conditions.

Also, when you see all those cases of “a screw was put back wrong and it caused catastrophic consequences”, you’re getting confirmation bias. You’re not seeing all the times that a screw was put back wrong but nothing happened and it was fixed at the next maintenance, or all the times that a screw was put back wrong but someone else fixed it.
