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

Redundancies, double- and triple-checks. Most plane-related disasters are generally a culmination of multiple things that have gone wrong, any of which, if done correctly, would’ve prevented the accident. Good maintenance and good pilot training and procedure can make planes extremely safe and reliable. Most systems on a modern aircraft have at least one or two backups. Properly trained pilots know how to diagnose and troubleshoot problems in the air; if one gauge is giving a suspicious readout, they know how to interpret the other gauges to determine what the true situation is.
