Real air traffic control audio of the Air Astana flight whose flight controls had been wired in reverse by a maintenance error. The pilots struggle to keep control while ATC tries to help.
Linked as a primary source recording for the reversed-controls incident in aviation safety discussions.

Sure, if you trust the correctness of the computer's software with your life and the lives of any passengers. There are popular apps now that do some of what you suggest, especially trip planning. I've seen enough bugs in my day job to want to at least verify the computer's work and have backup instruments, even if just my own senses. Aerospace software is known for relatively low bug counts[1] but also causing fatal crashes[2]. I trust my car controls to be correct and if they aren't I can brake to a stop if anything else seems off. (Unless of course the brakes stop working!) But since you have to take off to fly, you might not realize you can't control the plane until it's already at dangerous speeds.[3] 1: [LINK] 2: See [LINK] sections on Space, Military, and Transportation for examples. 3: Amazing story about an airliner that took off not knowing its controls had been reversed (a maintenance mistake). Pilots declared "MAYDAY plane is completely uncontrollable we plan to ditch" but eventually figured out how to fly the reversed controls and landed it safely—super impressive. this video

Air Astana Flight 1388 [LINK] "While all on board were shaken, there were no injuries apart from one passenger who suffered a leg injury." This must be the understatement of the century if you look into the details of what the crew went through. VASAviation Video: this video Final Report: [LINK]
Slightly off-topic: This is an ATC recording where pilots lost control over the aircraft. Figuring out what to do when the aircraft goes to random directions, they ask for the direction of the ocean to ditch in. Because of low visibility they have no idea where they are going. The description suggests that during maintenance, some steering control was attached in the wrong way. this video In this case, the pilots have like an hour to figure out how to control the aircraft.
